Abstract : A natural way to compute photonic dispersion relation is to restrict the parameters to the edges of the irreducible Brillouin zone (IBZ), which has been formalized as a dangerous simplification. We propose a novel method based on polynomial interpolation to approximate band functions in the whole IBZ. The importance of IBZ interiors, the need to reduce computational cost and our analysis of the regularity of band functions illustrate the necessity and feasibility of our method.
