The physics interfaces in this module form a complete set of simulation tools for electromagnetic wave simulations. Add the physics interface and study type when starting to build a new model. You can add physics interfaces and studies to an existing model throughout the design process. In addition to the core physics interfaces included with the basic COMSOL Multiphysics license, the physics interfaces below are included with the RF Module and available in the indicated space dimension. All physics interfaces are available in 2D and 3D. In 2D there are in-plane formulations for problems with a planar symmetry as well as axisymmetric formulations for problems with a cylindrical symmetry. 2D mode analysis of waveguide cross sections with out-of-plane propagation is also supported.
