We demonstrate that one-dimensional photonic crystal structures (such as multilayer f ilms) can exhibit complete ref lection of radiation in a given frequency range for all incident angles and polarizations. We derive a general criterion for this behavior that does not require materials with very large indices. We perform numerical studies that illustrate this effect.
