Electromagnetic Waves in Lossy Cold Magnetized Plasma
Application ID: 141091
A circularly polarized GHz wave is incident on a layer of cold magnetized plasma. Depending on the operating frequency and plasma state, the incident wave can excite a set of waves with different polarizations. The resulting reflection and transmission characteristics can be of interest for satellite communication applications.
From an RF perspective, cold magnetized plasma can be described as an anisotropic dielectric medium, with dielectric tensor components that depend on the external DC magnetic field and the electron density profile.
In COMSOL Multiphysics®, spatially varying plasma properties can be readily incorporated, the corresponding anisotropic dielectric medium can be specified, and the excited waves can be studied through the reflection and transmission spectra.
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.
