| Abstract: | Generalized ray expansion (GRE) method was used to study the problem of electromagnetic scattering by open cavities. The GRE method was briefly described,and a method of subaperture gridding was addressed which proved to be simple and efficient. Numerical results attained by this method were presented. Compared with the results from SBR methods, GRE method is more precise and efficient. |
