Hello,
I was trying to simulate the given picture's FSS structure in CST. I have drawn the structure, but I am struggling on how to make the port connection for this structure in CST. I have seen many tutorials but all of them contained only one metamaterial. Can anyone tell me how to give port connection on an array of metamaterial, so that I can find the figure shown in the picture?
Hey Md. Sadman Sakib Chowdhury Manjur
Can you define a floquet board over the entire array? you will include more modes to capture the increased size of the box but if you're looking for boresight performance you can still get that from the TE and TM modes.
You can use an infinite plane wave excitation from any direction you choose, which may be what you want. You can have far-field results.
If it has a ground plane and you are looking at propagation across the array then you can use a waveguide port full width along one of the edges, from the ground to several board thicknesses above the top of the board. You can choose which or how many modes to use.
