    Cited by:  Papers (5)
    Request Permissions | Click to expandAbstract | PDF file iconPDF (496 KB)  

    The design of a bandstop filter in nonradiative dielectric waveguide is described. The filter makes use of side-coupled guides to realize an equivalent of an open-circuited shunt stub and transmission-line section. Theoretical and practical results of the coupled lines as well as the filter performance are presented. View full abstract»

    The effect of ignoring complex modes on the solution of finline discontinuity problems is investigated. It is shown that the modal energy distribution at both sides of the discontinuity may be greatly affected by overlooking complex modes, even if they are not strongly excited. lt is also shown that disregarding only one mode of a pair of complex modes, while taking the other into account, results...

  • Wave Coupling Between Parallel Single-Mode and Multimode Optical Fibers

    A directional coupler composed of a single-mode optical fiber and a multimode optical fiber has been considered to be capable of serving as a drop/insert device of a node in optical fiber Iocal area networks. It should couple almost all the local transmitter power into the multimode fiber bus, while removing only a small fraction of the optical power from the bus through the single-mode fiber. In ...

    The purpose of this paper is to review the status of magnetostatic wave (MSW) resonators and to describe, in detail. the theory of operation of the recently developed straight-edge resonators. These resonators are based on magnetostatic waves propagating in high Q cavities fabricated in thin ferrimagnetic films. The resonance frequency of these resonators can be tuned via a bias magnetic field. Th... View full abstract»

    A wide-band monolithic GaAs bridge-T variable attenuator has been used with a monolithic GaAs active power splitter to form a compact 1-10-GHz leveling loop having a minimum 9-dB leveling range with buffered output. The attenuator internally optimizes input and output return loss over a 1- 10-GHz bandwidth by the use of an on-chip GaAs op-amp. The active power splitter provides unity gain to each ...

  • Characteristics of Multiconductor, Asymmetric, Slow-Wave Microstrip Transmission Lines

    Spectral-domain technique has heen applied to analyze multiconductor, asymmetric, slow-wave microstrip lines. It is observed that 1) the coupled slow-wave microstrip line on a two-layer substrate may have substantially different propagation constants for even and odd modes and 2) the slow-wave factor of an odd mode of coupled microstrip lines on a three-layer substrate may be equal to or larger th...

  • Coherent RF Error Statistics

    Cited by:  Papers (8)
    Request Permissions | Click to expandAbstract | PDF file iconPDF (824 KB)  

    RF error statistics for power, voltage, and phase are derived under the assumptions that the error component is coherently related to the desired signal, that its magnitude is constant, and that its phase is equally likely and uniformly distributed from 0 to 360°. The error statistics which result from these assumptions have nonzero mean values for power and voltage and standard deviations wh... View full abstract»

    We study the effect of the relative convergence problem on the transmission matrix formulation of cascaded discontinuities. A numerically efficient modified formulation satisfying the edge condition is presented. Application is in the analysis of waveguiding structures in which a number of conductors are placed on various interfaces. Numerical results are presented for double-ridged waveguides and...

    The application of molecular beam epitaxy (MBE) and X-ray lithography for the fabrication of monolithic integrated millimeter-wave devices on high-resistivity silicon has been investigated. Process compatibility and the retention of high-resistivity characteristics were measured using the spreading resistance method and Hall measurements after various process steps. Microstrip resonators of ring a... View full abstract»

    All-pass network techniques have made it possible to realize very small monolithic lumped active phase shifters with decade bandwidths, high yield, and relative phase stability, even when the device parameters vary +-20 percent. We have successfully demonstrated fully monolithic first-order networks (at 250 MHz) and second-order networks (at 4 GHz). View full abstract»

    A powerful modeling technique which exploits the theoretical properties of the l1 norm is presented. The concept of multicircuit measurements and its advantages for unique identification of parameters are discussed. Self-consistent models for passive and active devices are achieved by an approach that automatically checks the validity of model parameters obtained from optimization. A se... View full abstract»

Aims & Scope

The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design..
