    The direct current injection (DCI) Method offers in principle an advantage as an EMC test method to test systems against radiated low frequencies. This advantage has lead EADS-military air systems to the plan to use this method also for higher frequencies and to eliminate the restriction to test only to the first half wave resonance. Therefore a research program with the German Federal Office of Military Technology and Procurement (BWB) was raised in 2003 to evaluate the multiple use of DCI for indirect lightning, HIRF (high intensity radiated fields) and EMP (electromagnetic pulse).

    In this paper a methodology for taking into account the frequency dependence of a possible referencing (grounding) techniques in LTCC boards for satellite applications is presented. The aim of this work is to analyze and compare the input impedance and S-parameters values for different strategies of inter connection of the reference planes among them. The numerical analysis presented has proven the importance of the lateral metallization set up in the LTCC board working into a metal housing. For board used stand alone the lateral metallization can be replaced by an adequate density of vias stitching among the planes. The modelling agrees well with real grounding solution.

    Object of this paper is the signal integrity analysis of printed circuit boards with electromagnetic bandgap structures. In particular the signal quality of single-ended and DIFF lines is discussed both in time and frequency domain (S-parameters, TDR and eye-diagrams). Two different configurations (two dimensional and three dimensional) of electromagnetic bandgap structures are analyzed by means of a three dimensional full wave field simulator based on the finite integration technique. Results show a consistent improvement of the signal integrity when DIFF signaling is used, while keeping the typical advantage of noise mitigation due to electromagnetic bandgap layers.

    With the increasing numbers of transistors in todaypsilas die as well as incorporating mixed technology (i.e. analog, RF, digital, and power), large scale devices with their large switching currents create internal voltage drops due to the package design (i.e. wire bond or flip-chip) that can be a source of common mode noise. The normal lumped components, the printed circuit boards, the harnessing, and the packaging are well known contributors and there are various measurement techniques to identify these noise sources. However, what is lacking are some measurement techniques applicable specifically for determining if a large scale integrated circuit type devices could be a noise source. This paper will look at a couple of proposed techniques specifically for the chip level. View full abstract»

    Radiated emissions testing below 100 MHz in a semi-anechoic chamber presents a measurement repeatability challenge. In 2007, the Department of Defense revised MIL-STD-461, its electromagnetic interference standard. Among the changes, MIL-STD-461F introduced a new RE102 test configuration, where the rod antenna base is bonded to the ground plane through the cable shield and the height of the antenna is lowered. This RE102 setup is used for testing both bench-top and floor-standing equipment. No change was made to the biconical antenna test setup. With the proliferation of electromagnetic field analysis software, it is now possible to model, compare, and analyze the RE102 setups from MIL-STD-461E (two configurations) and from MIL-STD-461F (one configuration). It is also possible to investigate the impact of many undefined variables, including the chamber size, the test bench size, and the type of absorber used in the chamber. This paper compares and analyzes the results from computer simulations of the MIL-STD-461E and MIL-STD-461F RE102 test configurations from 10 kHz to 100 MHz. View full abstract»

    Object of this paper is the analysis of a conformal wire antenna used for the detection of stolen cars. The antenna operates in the low frequency range 0-300 MHz and it is located on the top part of the metallic chassis, over the back tire. Details on the simulation model are provided and results are validated by comparing different numerical methods: time domain (Finite Integration Technique and Transmission Line) and frequency domain (MoM). In particular the near field (surface current distribution on the vehicle) and the farfield results are calculated for the frequency value of 170 MHz and a matching network is also designed for the same frequency value in order to minimize the return loss of the antenna.

  • Detecting E and H fields with microstrip transmission lines

    Microstrip-like transmission lines are used to detect transient electric and magnetic (E and H) fields. Theory and experiment are compared for three different cases. The method can detect E and H fields on a ground plane, or may be integrated into a closed platform for E-H measurements during EMC testing. An application example using a desktop computer is shown. In situ measurements in a closed platform during EMC testing show that system ESD failures are caused by E-H fields, and not by direct voltage or current stress. Therefore, E-H field information measured by using microstrip-like transmission lines on PCBs in a closed platform during EMC tests will give insights to the exact nature of system failures due to ESD.

    The phase center location is used to determine the gain for horn antennas using the three-antenna method. The phase center of a pyramidal-horn antenna in the 18 to 26.5 GHz frequency range was calculated using the finite integration method, and then the gain was measured by using the distance between phase center locations obtained from this calculation. The measured results of the gain on the basis of the phase center location were in good agreement with the theoretical values. The uncertainty (k = 2) of the measurement was 0.13 to 0.16 dB in the given frequency range. View full abstract»

    The application of a parallelized multilevel fast multipole method (MLFMM) is described and illustrated through examples for the solution of large scale and complex EMC problems. Furthermore, to reduce the modeling complexity of such EMC problems, we propose a combination of field with network theory to split large problems into smaller sub-problems which can be analyzed individually and then again assembled together by means of network theory.

    In this paper to obtain of electromagnetic field distribution inside loaded enclosure with aperture, we present hybrid formulation which combines method of moments (MoM) and vector finite element method (FEM). While FEM is used for solving electromagnetic fields inside of the enclosure, MoM is used for solving the surface integrals related with the aperture field components using equivalent surface currents. To obtain efficiency of the proposed method, first applied to empty enclosure and the results are validated by comparing with literature. Then the method applied to loaded enclosure Shielding effectiveness, stored electrical energy and dissipated power in load are examined. View full abstract»

  • Signal integrity analysis of a 26 layers board with emphasis on the effect of non-functional pads

    Aim of this paper is the signal integrity analysis of multilayer boards with emphasis on the effect of non-functional pads. In particular it is demonstrated how removing the nonfunctional pads to reduce the coupling mechanisms of the pads with the planes above and/or below can not be considered a general rule of thumb due to possible larger impedance variation (TDR). Accurate and reliable numerical simulations are in this case really important in order to correctly determine the impact of those non-functional pads on the signal integrity. A 26 layers board is analyzed by simulating with a three dimensional EM field solver a portion of the original Allegro file. View full abstract»

    The effect of induced voltages due to electromagnetic pulses is studied with the combination of commercial electromagnetic simulation software (MEFISTo) and uncertainty modeling. The uncertainty is introduced using the Unscented Transform technique for two random variables: the relative permittivity and conductivity of the soil. These were modeled as independent random variables with uniform distribution. The results were the statistical moments of the induced voltage (expected value and standard deviation) as well as an estimate of the cumulative distribution function. View full abstract»

    Correlation between radiated emission from chassis with PCB and the junction current which is the current flowing through screws connecting PCB GND to chassis GND was investigated, and new technique to reduce the junction current was proposed. The measurement results of the junction current frequency spectra showed strong correlation with the emission from chassis with PCB. Also investigation using meshed LCR network SPICE model of PCB and chassis was performed. The calculation results of the junction current showed good correlation with measurement results for frequency spectrum and it suggested that the closer to screw bypass capacitor is placed, the lesser current flows through junction. That new concept was validated by actual measurement and the results of radiated emission showed 19 dB improvements at 320 MHz. View full abstract»

    The scaling of copper wires and the increase in signal switching speed produce transient crosstalk coupling between interconnect lines, which causes overshoots and additional time delay. Nano-interconnects made by single wall carbon nanotube (SWCNT) bundles can be good candidates for VLSI circuits. In this paper SWCNT bundles are simulated by means of the multiconductor transmission line (MTL) model and the equivalent single conductor (ESC) one, which is derived by applying a concurrent multiscale approach. The output voltages to fast input step voltages are predicted considering a different number of conductive tubes in the bundles and different values of the load capacitance. The sensitivity analysis of the crosstalk effects is performed. The 50% time delay of the output responses is computed for the considered nano-interconnect configurations. The results obtained by applying the MTL model and the simplified ESC approach are in good agreement. View full abstract»
