Department of Electrical and Computer Engineering ECSE 352 Electromagnetic Waves and Optics Module 4: Waveguides and antennas 4.1 Electromagnetic waves in transmission lines References: Section 14.1 @AGK 4.1-1 Overview So far we have considered two rather restrictive situations: voltages and currents on transmission lines and plane electromagnetic waves in free-space In this final on transmission lines and plane electromagnetic waves in free space. In this final module of the course we will extend our analysis to include two very important topics: waveguides and antennas. In both cases we will be applying all of the concepts that we have already developed. In the first class of this module we will h i i li i d h l d return to the transmission line in order to see how voltage-current waves and electromagnetic waves are directly related.
