How to design metamaterial in transmission mode.

[@wilfridrm9679]

Hello sir, I have a concern. Why do you divide the length of the metasurface by 2 (W/2) for the background properties at the lower and upper Z distance? Is it necessary? And why don't you leave it as open boundary conditions (add space) on the boundary conditions?

hello sir how we can simulate an ultrasonic distance sensor in cst can you make a video please?

Can u make a tutorial on reconfigurable metasurfaces please

Yes, that would be great
