Dear Farhad, I must admit that maybe I do not fully understand your question, but anything is predicted by Maxwell equations should be possible in MEEP. In many cases my computations required MEEP to take into account the non-radiative electric or magnetic fields (such as when building a split-ring resonator in metamaterial, sharp tips, surface plasmons, surface optical phonons etc.) and the results were compatible with experimental or previously published values. So you may build as narrow cavities/gaps as the FDTD grid allows you and everything should be realistic. With proper subgridding, you may even define slits much narrower than is the grid unit. F. D.
