Hello Mariah,Â
The stackrt is recommended for multilayered structure. That being said, it will calcualte absorption and transmission for structures where are infinite in lateral y and y irentations. The same results will be returned for FDTD if your structure will have the same periodic structure. Please refer to this link for FDTD/STACK comparison:Â STACK-FDTD.
In your design it is better to use FDTD solver as you want to calculate transmission and absorption of a complex structure (stepped). I wouldn't say that the results returned from stackrt are not good, more likely different I reckon.
Thanks a lot in advance
Regards
Dimitris
