Multiscale Modeling in High Frequency Electromagnetics
Application ID: 43351
Multiscale modeling is a challenging issue in modern simulation. This occurs when there are vastly different scales in the same model. For example, your cell phone is approximately 10 cm, yet it receives GPS information from satellites 20,000 km away.
In these models we examine several multiscale solutions in COMSOL Multiphysics, all related to the problem of antenna to antenna communications over large distances. These models demonstrate coupling between the Electromagnetic Waves, Frequency Domain interface and both the Electromagnetic Waves, Beam Envelopes and Geometrical Optics interfaces.
These models are the focus of the Multiscale Modeling in High-Frequency Electromagnetics series on the COMSOL Blog.

This model example illustrates applications of this type that would nominally be built using the following products:RF Module Wave Optics 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 Specification Chart and make use of a free evaluation license.
