Wave propagation along transmission lines
Summary
In this lecture, we will describe the theoretical models and computational methods for the analysis of wave propagation along transmission lines.
Content
1. Transmission Line Theory
Hypotheses, overview of models, Transmission Line and Antenna Mode Responses, derivation of telegrapher's equations
2. Transient analysis for lumped source excitation
Transmission of a pulse on an ideal line, multiple reflections, Bergeron diagram, reflections for different types of loads
3. Wave propagation on multiconductor systems
Determination of line inductance parameters, determination of line capacitance parameters, incorporation of losses. Modal analysis.
4. Transient analysis for distributed source excitation : field-to-transmission line coupling
Derivation of generalized Telegrapher's equations for field-excited lines. Representation of source terms. Different formulations of field-to-transmission line coupling equations. Plane wave excitation.
