Bench for Measuring Electromagnetic Properties of Materials in Free Space in a Ultrawide Microwave Range

Abstract

Specialized measurement bench is developed for measuring reflection and transmission coefficients of electromagnetic wave of material samples in free space, complex permittivity and permeability of sheet samples, angular dependences of transmissivity of materials and temperature dependences of reflectivity of metal backed radar absorbing materials at a normal incidence of electromagnetic wave in the frequency range from 1 to 40 GHz.
