Mode Analysis for Electromagnetic Waveguides
Application ID: 108431
Mode analysis is a basic tool for a wide range of radiofrequency and wave optics calculations because it allows for the investigation of mode characteristics in complex waveguide structures. In this tutorial model, you can find two examples that demonstrate typical settings and best modeling practices for such a study.
In example one, you will see how to perform mode analysis for a coaxial cable. The goal is to define the characteristics of the main TEM-mode and the first higher-order TE11-mode in a range of frequencies.
In example two, you will learn how to perform mode analysis for a rib waveguide. The goal is to define various modes and their polarization at one wavelength for a range of a core width.
You can learn more about these models in our blog post "Mode Analysis for Electromagnetic Waveguides in COMSOL®”.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
