Dear MEEP users, I am trying to calculate the near field enhancement of a gold nanosphere. At the moment i only calculated the enhancement at a fixed wavelength using a continuous source. Now i want to calculate the enhancement at a broadband wavelength. I don't know about the next steps after hitting a sphere with a broadband pulse. How should i know that which value of the enhancement corresponds to which wavelength?I also read on the group that i should take a 4D Fourier transform. Can somebody tell me how should i perform a 4D Fourier transform? Thanks in advance. BR,Aaron
