anisotropic material

I would like to build an RF wave guide that consists of three regions the left and right are made of air and the middle is made of an anisotropic material where epsilon (permittivity) is constant, but mu (permeability) defined as a tensor (mu_x 0; 0 mu_y). So how to define those quantities in COMSOL?

To define anisotropic properties do the following:
1. Right-click “Electromagnetic Waves, Frequency Domain (emw)” node and select “Wave Equation, Electric”
2. Go to “Wave Equation, Electric” setting window and select middle layer in the “Domain Selection” section
3. Under “Magnetic Field” section:
-From the “Electric permeability” list, select “User defined” and “Diagonal”
-In the “mur” table, enter components of relative permeability tensor

Sergei
