Abstract :
The method of circular waveguide radiating into a layered medium is used for the determination of permittivity and permeability of materials. A better accuracy is obtained by the modelisation of an air gap between waveguide and material. The simultaneous determination of complex permittivity and thickness of the material is possible.
