# Waveguide Dielectric Permittivity Measurement Technique Based on Resonant FSS Filters

@article{Costa2011WaveguideDP, title={Waveguide Dielectric Permittivity Measurement Technique Based on Resonant FSS Filters}, author={Filippo Costa and Claudio Amabile and Agostino Monorchio and Enrico Prati}, journal={IEEE Microwave and Wireless Components Letters}, year={2011}, volume={21}, pages={273-275} }

A method to determine the dielectric permittivity of materials is presented. Such a method exploits the use of a low-cost frequency selective structure (FSS), transversally placed in a waveguide in the proximity of the sample under test. The presence of the additional dielectric placed close to the FSS leads to a shift of bandpass and bandstop resonance frequencies. The relationship between the frequency shift and the permittivity of the dielectric under test allows the determination of the…
