摘要
The minibands and minigaps in the transmission bands of one-dimensional photonic crystals have been studied through Bloch's theorem, the tight-binding method and calculations based on the transfer matrix method. The minigap depths are dependent on the resonance intensity within the layers of one-dimensional photonic crystals and can be manipulated through the incidence angle. For a special structure and incidence angle, a polarization-independent flattop band can be achieved.
