Measurement of complex permittivity and complex permeability by transmission: reflection method in waveguide / Surani Sujor

This microwave measurement of complex permittivity (ε*) and complex permeability (µ*) method involve measurement of Forward Transmission coefficient and Forward Reflection coefficients that result when a sample of dielectric material is inserted in a waveguide. Seven types of samples are use in this project. The samples are FGM-125, FGM-40, C1SR 50% / 50%, CISR 60% / 40%, CISR 80%/ 20%, Teflon and PVC. These dielectric and magnetic properties were measured by a measurement setup consisting of microwave network analyzer, coaxial cable and coaxial-to- rectangular waveguide adapters. Based on measured value, complex permittivity (ϵ*) and complex permeability (µ*) are calculated.
