I want to shoot light on the FCC ‘(111)’ side. But optiFDTD PBG Crystal structure can control azimuth angle. FCC 111 structure is similar to Hexagonal Close Packed lattice. source direction is z direction(tilt angle can control y direction). I think this is not enough. If possible, make the incidence ã…£light perpendicular to the FCC 111 surface. The rotation limitaion seems to let the structure limit the angle of incidence. So, i want to make mirror.
Thank you, Scott
