Abstract :
The inverse problem of determining the constitutive parameters of an Ω material is considered. The dispersive bianisotropic Ω sample is placed in a rectangular waveguide. All the constitutive parameters except one are reconstructed using the reflection and transmission data for some TEm0 and TE0n modes. The remaining one can be obtained, e.g., from reflection of normally incident plane waves. Numerical results for the reconstruction are presented.
