nageswara rao, you can increase PML layers with PML parameter. Ex - is a physical x-component of electric field, Gx and Fx - additional variables of UPML technique for FDTD, k_Ex_a and etc. - transformation coefficients of FDTD method

Yes, L in [meters].
UPML FDTD for TE mode needs three Index matrixes due to the fact that in FDTD Ex, Ey and Hz have different space grids. You may apply single Index, but it'll cause distortions at low space resolution.

Add pause(0.01) after drawnow if the animation output is very fast on your PC.

how can we select the number of PMLs?
what these parameters Ex,Gx,Fx,Hx,Bx, k_Ex_a,b,c,d are stands for?

Great!

Thanks for the correction of the TE mode, everything works fine now !
