C. Dinallo et al., A BEM FORMULATION FOR EFFICIENT AND ACCURATE ANALYSIS OF DIELECTRIC WAVE-GUIDING STRUCTURES - EXTENSION TO MULTIBOUNDARY TOPOLOGIES, INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, 8(5), 1998, pp. 355-366
A recently proposed formulation based on the boundary element method (
BEM) has been demonstrated to be very accurate and efficient for the m
odal analysis of arbitrarily shaped dielectric waveguides. This innova
tive approach is extended here to analyze any topology having multiple
contours and/or dielectrics, thus permitting a complete characterizat
ion for guiding structures that are frequently utilized in several app
lications at microwave, millimeter waves, and optics. Various tests va
lidate the excellent computational properties of this method even for
compound structures. (C) 1998 John Wiley & Sons, Inc.
