Abstract :
A coaxial line terminated by a circular waveguide of arbitrary radius filled by a layered material medium is studied. A full-wave analysis of the structure via a mode-matching formulation is outlined. The equations are valid for both dielectric and magnetic materials. The model allows the study of the junction as a nondestructive testing tool. With an accurate theory, this scheme may be used to measure both complex permittivity and permeability of the material
