Abstract

The effectiveness of the proposed CMP-based regularization is demonstrated via the characterization of a hemispherical dielectric resonator antenna with an air gap. The resonator is excited by a feed probe. The need for fine discretization around the feed is justified by the need for properly modeling the curvature of the feed probe and the distribution of fields around it. The article demonstrates the benefits of the proposed approach by comparing the residual error versus iteration number recorded by a TFQMR solver for the systems produced by standard MOM and CMP-based discretizations.
