reaches the minimum at ␾ ϭ 0, and the absorption deteriorates rapidly when ␾ increases. However, ␾ is a nonlinear function of the frequency of the incident wave, and the region between Ϫ␲/2 and ␲/2 corresponds to the forbidden frequency band of the HIGP. Thus, a broad absorption band can be expected if a proper HIGP with a broad forbidden frequency band is(More)
