Gaussian Beam on a Periodic Structure

Application ID: 115701


This shows how a Gaussian beam incident on a periodic structure can be efficiently simulated. This could be applied to structured surfaces like metasurfaces or diffraction gratings.

Because of superposition, only a single unit cell needs to be simulated. This can provide extremely efficient simulations even for beam waists that are much larger than the structure and/or wavelength.

This model example illustrates applications of this type that would nominally be built using the following products:
