Electromagnetic characterization of ceramic material produced with natural zeolite

Abstract

The aim of this study is to investigate the electromagnetic characterization of ceramic panel produced with natural zeolite via considering the frequency-dependent transmission (T), reflection (R) and absorption (A) coefficients. For this purpose, first of all, frequency-dependent complex dielectric values(dielectric permittivity and tangent loss) of material are measured via LCR meter and complex dielectric values used in three dimensional(3D) electromagnetic simulation tool. Then, Debye parameters such as static permittivity(epsilon(s)), optic permittivity(epsilon(infinity)) and relaxation time(tau) are derived by using genetic algorithms. Finally, to validate the simulation results, T, R and A coefficients obtained from simulations are compared with frequency-dependent T, R and A values calculated by using the transmission-line equation.
