2D binary grating consists of a cylinder #29

Thanks for the excellent work. I am a new on metasurface. I wanna define a meta-atom consists of a cylinder with a glass substrate, which is a periodic unit of a 2D binary grating, and I wanna get the transmittance of the plane wave with different frequencies. Here is the model I made in Lumerical FDTD solutions. Is there any example that is similar to this task that I can refer to?

lbolla commented 5 years ago

Sorry, there are no examples of such structures in EMpy. You mention FDTD: EMpy does not implement that method. What method from EMpy would you like to use?

BrandonHanx commented 5 years ago

I just modeled the structure desired using FDTD. All methods which can solve EM response will be ok for me, such as FDTD, RCWA or FEM and so on.

lbolla commented 5 years ago

EMpy's RCWA is 1D and FEM is not implemented. I used to use an algorithm based on Bessel function expansion to solve such structures, but it's not included in EMpy.

Ok, I get it. Thanks anyway.
