An inverse scattering problem in metallic waveguides filled with bianisotropic material

In English

Författare

Summary, in English

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. Some

information can also be obtained on the cross-sectional shape of the

modes, but it remains an open question if this information can be used

to characterize the material. The method is illustrated by numerical

examples, determining the complex permittivity for lossy isotropic and

anisotropic materials.
