A new full-wave integral equation method for the analysis of coplanar strip circuit using the mixed-potentials eigenfunction expansion technique

Theoretical results obtained by a full-wave integral equation formulation using the mixed-potentials eigenfunction expansion technique are presented. This formulation can analyze a 3D coplanar strip discontinuity structure on a finite-width substrate. As an example of a reduced structure analyzed by the method, the theoretical results for a microstrip discontinuity problem are validated by comparing them with those obtained by the spectral-domain approach program LINMIC/sup +/.<
