[Meep-discuss] Hexagonal photonic crystal band structure with Meep

hello Dear Steven and Meep users Up to now, I have run Meep for photonic crystals with square lattice and the results are the same as the MPB. I have tried to do this method for hexagonal lattice. computational cell is a rectangle with size of a*(a*sqrt(3)) with a cylinder at its center and four o

Good mornig, I'm an italian student and I'm simulating some properties of quasicrystals. I'd want to compute the efield distribution in some geometry (two slabs of quasicrystal) and later to use the distribution as a initial condition (like a source) for a second simulation with a different geomet

[Meep-discuss] field synchronization

2010-12-24 Thread Özgür Önder KARAKILINÇ
Hi meep users, I have two sources in my structure. One of them is Ez field, the other one is Hz field. I want to get fluxes with add-flux function. In wiki page, fields are synchronized automatically in flux-in-box and field-energy-in-box routines. But I am using add-flux function to get fluxes.
