MATLAB code for permittivity calculation using Nicholson-Ross-Weir algorithm.

This MATLAB file contains code that implements the Nicholson-Ross-Weir (NRW) algorithm to calculate the permittivity (dielectric constant) of FR4 material. The code likely processes s-parameter data (potentially obtained from network analyzer measurements) to extract the permittivity value. This supporting file provides details about the specific algorithm used for permittivity calculation in our research. (M)
