An inverse scattering problem in metallic waveguides filled with bianisotropic material
This paper presents an analysis with the aim of characterizing an arbitrary linear, bianisotropic material inside a metallic waveguide. The result is that if the number of propagating modes are the same inside and outside the material under test, it is possible to determine the propagation constants of the modes inside the material by using scattering data from two samples with different lengths.
