Metamaterial unit cell desing-simulation?

04 November 2022 1 2K Report

Hello everyone,

is there a generic rule in simulation setup of metamarials cells when it comes to what should be at the bottom of the substrate?

Thanks for your responses.

Mike Albert

The bottom layer should be thick enough that the evanescence wave is almost gone by the bottom surface. To the degree that is not possible, you do not want a fake reflection in your calculation. Set the boundary condition to absorb the remaining field.
