    A tutorial discussion on the receiving and scattering properties of antennas is presented. The objective of this work is to provide a comprehensive tutorial overview of the subject, in conjunction with circuit calculations and numerical simulations that illustrate the fundamental concepts of how antennas behave as both receivers and scatterers of electromagnetic fields and power. The paper begins ... View full abstract»

  • A New Chu Formula for Q

    The Chu fundamental limitation on Q for electrically small antennas is well known and widely used. However, Chu did not include energy stored inside the hypothetical enveloping sphere. Exact calculation of total stored energy by Thal gives a new Q, which should better match well-designed electrically small antennas. The TM- and TE-mode Q formulas are derived, and a simple approximate form for the ... View full abstract»

  • Parallel MoM Using Higher-Order Basis Functions and PLAPACK In-Core and Out-of-Core Solvers for Challenging EM Simulations

    Typically, the problem size that can be solved by the Method of Moments (MoM) is limited by the amount of RAM installed in the computer. To reduce the number of unknowns for MoM, higher-order polynomial functions have been introduced as the basis functions. To extend the capability of the MoM code, this paper presents a new development: the use of a new parallel out-of-core solver called PLAPACK. ... View full abstract»

    In this paper, the Finite-Element Method with weighted extended basis splines (web-spline) is described and used to obtain electromagnetic fields. This new approach is applied to two-dimensional rectangular, circular, and coaxial waveguides. The electric- and magnetic-field distributions of some modes are shown. The approximated solutions of web-splines are compared with the standard Finite-Elemen... View full abstract»

  • On the Relationship Between Compressive Sensing and Random Sensor Arrays

    Random sensor arrays are examined from a compressive-sensing (CS) perspective. It is demonstrated that the natural random-array projections manifested by the media Green's function are consistent with the projection-type measurements associated with compressive sensing. This linkage allows the use of existing compressive-sensing theory to quantify the performance of random arrays, of interest for ... View full abstract»

  • One-Minute Rain-Rate Contour Maps for Microwave-Communication-System Planning in a Tropical Country: Nigeria

    Rain attenuation is the dominant propagation impairment for high-frequency microwave systems. System design therefore requires the knowledge of the one-minute integrated rain-rate cumulative distribution function over the coverage area in order to determine the appropriate transmitter and receiver characteristics. This paper presents a set of rain-rate contour maps, useful for link and network pow... View full abstract»

    An L-band switched directional/omnidirectional antenna module, consisting of a four-monopole antenna, a switched beamforming network (SBFN), a matching network, and an interface, is described. The antenna includes four folded monopoles, parasitic elements, a special base plate, a common capacitive top hat, and a radome. The special switched-line 0°/180° phase shifter of the switched beamforming ... View full abstract»

    The autumn is upon us: at least in East Lansing, Michigan, USA, the weather is getting cooler as we await the onset of snow (and plan our escape from the winter to warmer locations, like the Carribean Islands). Perhaps I will see you at an upcoming conference. I hope if you are a Chapter officer, you can take a few moments to chat with me about how your Chapter activities faired this year View full abstract»
