Thanks Sir for your reply. This is solved. Now, what I'm facing that for a non zero kz value, there will be no TE or TM polarization. The fields for a particular band at a certain point should be coupled. is there any way in mpb to map that coupled field? (I tried that but the results seem to be not reliable)
(eg. if for an inplane condition, if we search for e field distribution for a band (say band 2) at a point (say K point) of a a hexagonal PC, mpb returns e field distribution) Thanks Subir Subir Majumder On Thu, Feb 12, 2015 at 11:30 PM, silvia...@ua.pt <silvia...@ua.pt> wrote: > Hello, > > if you need to put non-zero values for kz in MPB, for instance in an > hexagonal lattice, it can be done like this: > > (set! k-points (list (vector3 0 0 kz_mpb) ; gamma > (vector3 0 0.5 kz_mpb) ; m > (vector3 (/ -3) (/ 3) kz_mpb) ; k > (vector3 0 0 kz_mpb))) ; gamma > > where, kz_mpb in fact is unitless, it is: > kz_mpb = kz.a/(2pi), > where kz can be measured in [m^-1], and a is the lattice periodicity in > [m]. > > SÃlvia M.G.
