Plotting with Floquet periodicity

Hi all,

I am currently working on a model in the acoustics module that has similarities with the RF anechoic chamber model:
www.comsol.com/blogs/modeling-rf-anechoic-chamber-using-periodic-structures/

In my model I also use the Floquet periodic boundary conditions to achieve a 3D periodic structure. I was wondering if it is possible to plot the acoustic pressure over the periodic structure in 3D? I have managed to accomplish this in a 2D model using:

acpr.p_t*exp(-i*arr1cellx*kx*W)

, where W is the width of the model.

Is there a similar expression in COMSOL to do this in 3D?

Best regards,

Niels
