Coaxial to Waveguide Coupling
Application ID: 1863
Feeding a waveguide from a coaxial cable is a straightforward way to achieve electromagnetic waves inside a waveguide. Due to its small size and circular shape, the cable contributes significantly to the overall size of the problem. It is therefore necessary to keep the cable as short as possible.
This model shows how to use pairs and the Port boundary conditions to feed a rectangular waveguide. The port condition can be placed directly at the surface where the cable enters the waveguide, and only a short cable part, modeled as a perfectly matched layer (PML), is subsequently necessary.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
