Abstract :
A simple non-destructive method to measure the complex permittivity of materials is described. It uses an iris terminated resonant section of waveguide in contact with the metal-backed sample. A numerical analysis of the structure permits one to relate the measured resonance characteristics to the sample permittivity.
