Abstract :
A hybrid measurement method is proposed for the accurate characterization of complex permittivity and permeability of low loss materials. A transmission/reflection method is considered for the characterization of the real parts of the permittivity and permeability of a low loss composite material. Then measured quality factors of a cavity loaded by a sample of composite material at two different locations are used to calculated the imaginary parts of the permittivity and permeability. Simulation indicates that the accuracy of the imaginary parts of the permittivity and permeability may be increased by employment of resonant cavity measurements.
