A rectangular waveguide is a hollow metal tube filled with dielectric with a rectangular cross-section. The rectangular cross-section has one side that is one dimension greater than the other. It is commonly used to guide electromagnetic waves.
In this module, we will focus on the governing equations of the rectangular waveguide using Maxwell’s equations. This module covers why electromagnetic waves travel in different propagating modes inside the waveguides, why some modes do not exist in the rectangular waveguide, and why it acts as a high-pass filter.
