Is it possible to do it with combination of PML and ports? For a lossless rectangular straight waveguide, the resulting Electric Field Norm should be uniform along the waveguide. Most tutorial examples, like circulator, Hi, Everyone, I am new for using comsol, and firstly I built a easy model to learn. It is a 2D slab waveguide (see attached ). By mode analysis, I found the effective mode index obtained by comsol is different with the value obtained by analytical solution. In comsol mode, the infinite direction is set as PBC with A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step-index fiber. This model solves for the effective index and fields of a dielectric slab waveguide and compares the solution to analytic results.

Dielectric Slab Waveguide. Introduction. A planar dielectric slab waveguide demonstrates the principles behind any kind of dielectric waveguide such as a ridge waveguide or a step index fiber, and has a known analytic solution. This model These examples show how to model a rectangular waveguide for microwaves in 2D and 3D. A single hollow waveguide can conduct two kinds of electromagnetic waves: transversal magnetic (TM) or transversal electric (TE) waves. The models examine a TE wave that has no electric field component in the direction of$
