Abstract

This paper presents a new method for the determination of the reflection and transmission characteristics of dielectric materials that are the parameters for the calculation of the complex permittivity using the Nicolson-Ross-Weir (NRW) method. In transmission line methods, most widely used methods for broadband permittivity measurements, the NRW method gives a stability problem for low-loss dielectric materials near the thickness resonance frequencies. The proposed method successfully removes the problem using a relationship between the reflection and transmission characteristics. The proposed method is a new iterative transmission/reflection method applicable to permittivity measurements using arbitrary sample lengths in wide-band frequencies.
