For lossless periodic structures with a proper symmetry, the transmission and reﬂection spectra often have peaks and dips that are truly 100% and 0%, respectively. The full peaks and zero dips typically appear near resonant frequencies, and they are robust with respect to structural perturbations that preserve the required symmetry. However, current theories on the existence of full peaks and zero dips are incomplete and diﬃcult to use. For periodic structures with a bound state in the…
