This paper explores the concept of using the resonant nature of complementary frequency selective surfaces (CFSS) placed in a waveguide to characterise the permittivity of homogenous dielectric materials. Electromagnetic simulations using the 3D FDTD software, Empire XCcel® have been used to characterise some of the properties of this CFSS-Waveguide technique and used in the extraction of the permittivity of these materials. The simulation setup, well-known extraction equations and their modified versions, along with the extracted results are presented in this paper.
