Application to a Quarter Wave Transformer Fulvio Andres Callegari fulvio.callegari@ufabc.edu.br 1 Centro de Engenharia, Modelagem e Ci¨ºncias sociais Aplicadas, CECS, Universidade Federal do ABC, Santo Andr¨¦, 09210-170, SP, Brazil A simple way to simulate a transmission line using a free software is developed. The line is simulated connecting in cascade a number of cells consisting of capacitors and inductors with appropriate values. This model was verified by reproducing numerical values of an example taken from the literature. https://pubs.sciepub.com/ijp/13/2/4/ijp-13-2-4.pdf Transmission Lines Characteristic Impedance Stationary Voltage Waves Impedance Matching
