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?

Can u make a tutorial on reconfigurable metasurfaces please

[@jokincifuentesantxia362]

Yes, that would be great
