Scattering by Multiple Arbitrary Circular Cavities Loaded in a PEC Plane
In this letter, an efficient solution based on the modal expansion method for the analysis of wave scattering from multiple arbitrary circular cavities placed in a perfect electric conductor is presented. Unlike most of the existing methods that employ the Graf's addition theorem, which brings serious problems, we employ the complex function method cooperating with multipolar coordinate transformation to match tangential fields in analyzed regions. Finally, unknown expansion coefficients are computed by solving the system of linear equations and the Fourier series. Some typical examples are given to verify the solution by the method of moments.
期刊介绍:
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
