A hybrid transfer-matrix finite-difference time-domain (FDTD) method is proposed for modeling the optical properties of finite-width planar periodic structures. This method can also be applied for calculation of the photonic bands in infinite photonic crystals. We describe the procedure of evaluating the transfer-matrix elements by a special numerical FDTD simulation. The accuracy of the new method is tested by comparing computed transmission spectra of a 32-layered photonic crystal composed of spherical or ellipsoidal scatterers with the results of direct FDTD and layer-multiple-scattering calculations.
提出了一种混合转移矩阵时域有限差分（FDTD）方法，用于对有限宽度平面周期结构的光学特性进行建模。该方法也可用于计算无限光子晶体中的光子带。我们描述了通过特殊的数值FDTD模拟来评估转移矩阵元素的过程。通过将由球形或椭球形散射体组成的32层光子晶体的计算透射光谱与直接FDTD和层多重散射计算结果进行比较，测试了新方法的准确性。
