Reconstruction of the constitutive parameters for an /spl Omega/ material in a rectangular waveguide

摘要

The inverse problem of determining the constitutive parameters of an /spl Omega/ material is considered. The dispersive bianisotropic /spl Omega/ sample is placed in a rectangular waveguide. All the constitutive parameters except one are reconstructed using the reflection and transmission data for some TE/sub m0/ and TE/sub 0n/ modes. The remaining one can be obtained, e.g., from reflection of normally incident plane waves. Numerical results for the reconstruction are presented.
