中文摘要：

用转移矩阵方法从理论上研究了光波在一维金属/电介质光子晶体中的传播特性.通常可见光在金属中的趋肤深度只有十几nm,所以在几十nm以上厚度的金属中是不能传播的.但可见光在由金属和电介质构成的一维光子晶体中传播时,即使金属的总厚度远远超过趋肤深度,仍然能够通过.单层金属膜的厚度越大,透射率越小,透射谱线的峰宽越窄.随电介质层的厚度增大,光子带隙向长波长移动.结构的周期数越大,透射率越小.但周期数并不能影响带隙的位置和宽度.

英文摘要：

The light transmission properties of one-dimensional metal-dielectric photonic crystals are studied theoretically by transfer-matrix method. Usually, a metal film whose thickness is in excess of dozens of nanometer is fairly opaque to visible light. However, the transmission of visible light is quite large when propagate in a metal-dielectric photonic crystals whose total thickness of metal film far exceeds skin depths. With the increase of thickness of a single metal layer, the transmission of light decreases and the width of the transmission spectrum becomes narrow. As the thickness of a single dielectric layer increasing, the photonic bad gap shifts to long wavelength. The larger period number, the lower transmission of light. But the period number has no effect on the position and the width of photonic bad gap.
