Extracting Resistance, Inductance, and Capacitance Matrices Using Finite Element Method

Abstract

In high-frequency and high-speed digital systems, minimizing signal interference, delay, and loss is crucial. Therefore, the role of multiconductor transmission lines (MTLs) is highly significant, and computational electromagnetics (CEM) are essential for analyzing their characteristics. In this study, electromagnetic simulations were performed in two- and three-dimensional multiconductor transmission lines using the finite element method. Subsequently, a postprocessing technique was used to extract resistance, inductance, and capacitance matrices. The accuracy of the results was verified by comparing the results with those of Q3D, a commercial electromagnetic simulation software.
