摘要
应用平面波展开法和时域有限差分法分析计算了二维方形光子晶体在太赫兹波段的带隙特征,并着重研究了影响太赫兹波段二维方形光子晶体带隙的因素。通过改变光子晶体的介电常数和截面半径得出了光子晶体带隙随这两种因素的变化规律,进而研究了太赫兹波段损耗较小的塑料和高阻硅两种材料构成的光子晶体带隙及光子晶体波导的传输特性。
The photonic band gaps of two dimensional square lattice photonic crystals are analyzed in terahertz range using the plane wave expansion method and the finite difference time domain meth-od. The simulation results indicate that the photonic gaps vary with the dielectric constants and radi-us of materials in the square lattice photonic crystal. Then the band gaps and transmitting character-istics of photonic crystal that based on the plastic and high-resistivity silicon are studied.
