energy band diagram calculation
Dear all,
After reading number of papers on photonic band gap calculation, I found that the calculation is always done for a particular direction. Say for example, if we consider a square lattice, we only consider the perimeter, rather than the whole area of the reduced Brillouin zone. Some argues that ω(k) for all other points within the reduced Brillouin will lie within the boundary set by the high symmetric points. But the answer still remained vague to me.
Can anybody explain to me the physics behind this???
Thanks
