# transmittance of Gauss beam

#1

How to set the fdtd file to get the transmittance of the sample when we change the Gauss beam energy?

Dear @M201670193

Can you elaborate more on this? I assume by Gauss beam you mean Gaussian?
Also, are you using nonlinear material? Are you looking into normalized transmission? Maybe you can upload your simulation file for a review.

Thanks
