ELECTROMAGNETIC SCATTERING FROM RADIALLY OR AXIALLY INHOMOGENEOUS OBJECTS

摘要

A computer program based on the method of moments approach is developed to compute electromagnetic scattering from axisymmetric objects. The object may consist of N linear isotropic homogeneous regions. These regions may be arranged axially and/or radially with the axis of symmetry. Surface integral equations (SIE) formulation, EAPMCHW, is used to formulate the problem. Other formulations can easily be incorporated in the computer code. Bistatic and monostatic Radar Cross Sections (RCS) for several benchmark geometries are computed. The computed results are verified by comparison with measured and exact calculated results. In some cases the self-consistency method is used to perform the verification. The measured and calculated data presented in this paper are expected to serve as benchmarks for other researchers in the field. [Vol. 7, No. 1, pp. 4-23 (1992)]
