Lecture

Transmission Line Coupling Models and Solutions

Description

This lecture covers the theory of transmission lines, including the presence of external electromagnetic fields, generalized Telegrapher's Equations, and frequency domain solutions. It extends to multi-conductor lines, discussing the equations of Agrawal et al. and the boundary conditions. The lecture also explores the solutions for a line excited by series voltage or shunt current sources, analyzing the reflection coefficients and determining unknown coefficients. Additionally, it presents examples of load responses and the induced current waveform, explaining the effects of distributed sources on the line. The homework involves extending the BLT equations to field-excited lines and analyzing the transient response for load currents.
