Summary:In the classical Nicolson-Ross-Weir electromagnetic material parameter extraction technique the effective material parameters are obtained through reflection and transmission measurements of a planar material sample. One of the advantages of this technique is that it provides the result over a broad frequency band with just one measurement. This technique, however, does not provide us unambiguous results of the effective permittivity and permeability but the correct solution needs to be found through an additional deduction process. Here we present a derivative of the Nicolson-Ross-Weir extraction technique that can overcome this problem related to the infinitely many branches of the solution.
