S-Parameter Conversion MATLAB

Resource Overview

This MATLAB code requires three input parameters: d (period constant in metamaterial thickness direction), f (frequency range), and S (scattering parameters obtained from CST or HFSS simulations). The implementation requires S-parameter data to be stored in an Excel file named "asd" placed in the MATLAB path. The Excel file must contain frequency values in the first column, real and imaginary parts of S11 parameters in the second and third columns, and real and imaginary parts of S21 parameters in the fourth and fifth columns respectively.

Detailed Documentation

This article explains how to utilize the provided MATLAB code to process key input parameters including the period constant d in metamaterial thickness direction, frequency range f, and scattering parameters S obtained from electromagnetic simulation software like CST or HFSS. The code implementation requires S-parameter data to be organized in a specific Excel format: the first column must contain frequency values, followed by real and imaginary components of S11 parameters in columns two and three, and real/imaginary parts of S21 parameters in columns four and five. The Excel file must be named "asd" and placed within MATLAB's accessible directory path.

For optimal utilization of this code, we recommend including additional datasets in your Excel file, such as calculations using different material parameters or geometric configurations, to comprehensively analyze system performance. The algorithm supports parameter variations and different computational approaches to enhance result accuracy. These suggestions aim to improve code usability and research efficiency by facilitating systematic parameter studies and comparative analyses through structured data input and processing routines.
