Permittivity and permeability, frequency and Temperature Wideband measurement setup

Today, we need to precisely know permittivity and permeability value of any kind of material in many domains. We know that temperature has a specific impact on behavior of material. Especially on radio frequencies and microwave applications like biomedical, aeronautics… Furthermore, moisture content in a material has a significant impact. Due to the important variation of temperature in many countries characterization measurement like Radar Cross Section measurement. In the case of radomes on aircraft we find many antennas which are exposed at very high temperature variation. In this way correlation between Temperature and electromagnetic characteristics became essential. In this paper, we propose a technical system to measure the influence of temperature on the dielectric permittivity and permeability on composite material.
