Vvs. Prakash et al., HYBRID METHOD OF ANALYSIS OF SLOT DISCONTINUITY IN A RECTANGULAR WAVE-GUIDE AND THE VALIDITY OF CIRCUIT REPRESENTATION, INTERNATIONAL JOURNAL OF RF AND MICROWAVE COMPUTER-AIDED ENGINEERING, 8(4), 1998, pp. 339-349
A novel analysis to compute the admittance characteristics of the slot
s cut in the narrow wall of a rectangular waveguide (also called edge
slot) is presented. The slot aperture field is expanded in terms of en
tire domain sinusoidal basis functions and is solved using Galerkin's
method. The computed results have been compared with the measured data
published in the previous literature to validate the present analysis
. The validity of representing the edge slot as a shunt element is exa
mined and an alternate way of representing the edge slot is suggested
as being more accurate. (C) 1998 John Wiley & Sons, Inc.
