Efficient analysis of planar circulators by a new boundary-integral technique
Abstract
The application of a new boundary-integral technique to the study of planar circulators in stripline/microstrip technology is described. The technique employs Green's second identity with plane waves as weighting functions and leads to a very efficient algorithm for the analysis of planar devices in anisotropic media. Extensive comparison is made with results from the standard contour-integral formulations with very good agreement between the two techniques. The new technique is more stable in the critical region (mu(sub eff) close to 0) and is somewhat faster.
