PRINTED-CIRCUIT ANALYSIS BASED ON THE EDGE-EFFECT BY A NEW MODE-MATCHING THEORY METHOD Mikio TSUJI and Hiroshi SHIGESA W A ABSTRACT A new mode-matching method is proposed here for printed-circuit analysis, which considers the field-continuity conditions via the aperture field expanded into finite series of singular functions. In this sense, our approach seems to be similar with the spectral

ELECTROMAGNETIC SCATTERING FROM INFINITE STRIP GRATING WITH INHOMOGENEOUS MATERIAL COATING USING A COMBINED SURFACE AND VOLUME INTEGRAL EQUATION FORMULATION Peter PETRE. ABSTRACT Gyula VESZELY -- A combined-field integral equation is developed to analyse electromagnetic scattering from planar flat strip and infinite periodically located strip grating with homogeneous and/or inhomogeneous

ELECI'RIC FIELD SINGULARITIES IN MICROWAVE INTEGRATED CIRCUITS (MIe) S. Marchettit and T. Rozzit* ABSTRACT 90° and 270° plane metallic corners occur in many discontinuties in microwave integrated circuits (MIC), such as impedance steps. The determination of the scattering matrix of the step by variational methods, for instance, requires some knowledge of E-field at the discontinuity. In

ANALYSIS OF THE SUPERCONDUCI1NG K. -So Kong, H. -Y. Lee and T. Itoh* ABSTRACT COPLANAR WAVEGUIDE This paper presents a conductor loss calculation of the high Tc superconducting coplanar waveguide (CPW) by using Phenomenological Equivalence Method (PEM) and two fluid model. In this method, the equivalent strip line is obtained by calculating the equivalent width and thickness of CPW by considerin
