try switching off the "metal" behaviour by e.g. imposing a purely real dielectric constant on your sphere, so that it acts as a pure scatterer, record the field in a few points, then redo the simulation with a metal sphere and see what changes

Problem with the Near Field Enhancement (Aaron Abbott) ---------------------------------------------------------------------- Message: 1 Date: Mon, 21 Mar 2011 11:01:01 +0100 From: Aaron Abbott <[email protected]> Subject: [Meep-discuss] Problem with the Near Field Enhancement To: <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" 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 -------------- next part -------------- An HTML attachment was scrubbed...
