Comparison of Formulations for RF Heating
Application ID: 115821
This model compares the results of five different formulations and approaches to solving an RF heating problem consisting of a coaxial cable inserted into a sample of lossy dielectric material. Results show that the different formulations agree over a wide frequency band.

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:
- COMSOL Multiphysics® and
- CAD Import Module and
- either the AC/DC Module, or MEMS Module
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.
