my project is a cylinderical mim waveguide and i used a magnetooptic material for dielectric layer. when i replace the magnetooptic layer by a isotropic dielectric the lumerical answers seems to be true. i can see the propagation lenght of waveguide when i simulate my project in fdtd 3d simulation.  

can i use the fdtd 3d simulation for observing wave propagation when i used anisotropic material?i defined my material using the code explained on the Lumerical website. the wavelenght is 1550 nano and propagation lenght is about 4 micron. cylinderical radius is about 500 nano
