Dear MEMS community, has anyone experience with ANSYS and simulation of nano-photonic devices? I was kind of surprised as I found out that it is not possible (using standard unit definition) to build-up models with dimensions in nanometer range. I would appreciate any comments on simulating of scattering problems in visible range on objects with wavelength-comparable dimensions. Also, I would appreciate any recomendations on some FTDT simulation tool providing some free-testing versions. Kind regards J.Kouba
