Hi all,
I have a question regarding Wavesim capabilities. I am a beginner to EM simualtions.
Can it be used for periodic structures (varying refractive index as cosine function in 16micron depth). I am using RCWA (Maxwells equations) for this which has to descretize a 16 micron thickness into hundreds of layers to give good result. I was wondering if wavesim will provide a faster solution for this. I am interested in polarisation, diffraction, reflection and transmission of my structure.
Thank you.
Hi, Imaad. Welcome to the Wavesim forum! If my understanding of RCWA is correct, it requires a constant refractive index in the z-direction (for each layer). Is that right? Assuming yes, Wavesim does not have this limitation, and you can assign a different refractive index for every pixel/voxel. I think there's some potential for improvement in speed or accuracy, or maybe even both! We can help you set up a simulation to test this.
