mode analysis for 2D slab waveguide
Posted Feb 21, 2013, 10:17 AM EST RF & Microwave Engineering Version 4.3a 6 Replies
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 continuity.
I appreciate you can give me some help.
