An improved technique for low-loss material complex permittivity and permeability determination from transmission-only measurements

Abstract

Abstract In this paper, a novel technique based on transmission-only measurements is proposed to determine complex permittivity and permeability of low-loss materials. The proposed method removes the influences of the sample thickness and avoids the resonances in the extracted parameters. Both the experiment and simulation are applied to present the advantages of the proposed method. Compared with the well-known Nicolson–Ross–Weir (NRW) method, the proposed method shows a good performance in resonance avoidance. Compared with the conventional method based on the transmission-only measurements, the proposed method shows a good performance in accuracy.
