Complex Permittivity and Permeability Measurement Method of Multiple Free-Space Incident for Structured Absorbing Materials

摘要

In this paper, a novel technique is presented for measuring permittivity and permeability of honeycomb structured absorbing materials by multiple incident free-space method. The measurement system consists of transmit and receive horn antennas mounted on an arch frame, a network analyser and a flat test bench. The reflection coefficients S
