I have been trying to run simulations with Lumerical&#8217;s RCWA script to calculate device reflection and transmission for simple optical stacks. While my results for TE are fairly accurate and converge quickly, my results for TM polarization take a large amount of modes to converge (still doesn&#8217;t converge after 600 modes). I am wondering whether anyone else has ran into this problem and what they have done to solve it.
