Lossy Circular Waveguide
Application ID: 1418
In mode analysis it is usually the primary goal to find a propagation constant. This quantity is often, but not always, real valued; if the analysis involves some lossy part, such as a nonzero conductivity or an open boundary, the eigenvalue is complex. In such situations, the real and imaginary parts have separate interpretations:
- The real part is the propagation constant
- The imaginary part is the attenuation constant, measuring the damping in space
This tutorial shows how to set up a mode analysis with lossy metallic walls for a waveguide. The attenuation in dB per km is extracted for several modes.
This model example illustrates applications of this type that would nominally be built using the following products:RF Module
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 Tabela de Especificações 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.
