[Meep-discuss] Figure of Merit (FoM) calculation

2012-06-16 Thread cecil chalmers
Dear Users, I am simulating gold nanosphere dimer as an example. I want to calculate the Figure of Merit. The figure of merit is commonly defined as the resonance shift upon a change in the refractive index of the surrounding dielectric normalized by the resonance line width. Can anybody expl

Dear MEEP users, The basic FDTD algorithm is based on a constant cell size grid. Thus, if you want to resolve a small object, for example sphere somewhere in the problem space, you have to use that some cell density everywhere, even in the free space regions. Can some body tell me, how
