Abstract
The problem of electromagnetic transmission through an arbitrarily shaped aperture in an arbitrarily shaped 3-D conducting surface enclosing homogeneous chiral material is investigated. To solve the problem numerically, the surface equivalence principle and the method of moments are used. The validity of the procedure has been checked by comparing the numerical results to other available solutions whenever possible. Numerical results for the physical electric current on the surface of the obstacle, the internal field, and the bistatic radar cross section are presented for the examples of a sphere and a finite cylinder with circular apertures. These results are computed for various electrical sizes, permittivity values, chirality values, and aperture sizes. © 1963-2012 IEEE.
