The investigation results show that the band gap of the photonic crystal made of LHM is wide and multi-transmittance peaks appear in the forbidden band.

研究结果表明：一维右手材料和左手材料构成的光子晶体具有宽禁带的特点，禁带中出现多个共振透射峰。

The transmittance of light is forbidden in a wavelength range called photonic band gap. Photonic crystals have broader application prospect than common optical materials.

光子晶体的基本特征是具有光子带隙，频率落在带隙中的光将不能传播，这使其比普通光学材料具有更广泛的应用。

Some Eurocrats suggest that the philosophical gap reflects the American constitutional tradition that everything is allowed unless it is forbidden, against the Napoleonic tradition codifying what the state allows and banning everything else.
