我们分析了非金属周期结构对于微波区域电磁波的带阻特性。目标频率是 2.4 和 5 GHz 频段，这两个频段在日本的无线 LAN 中广泛使用。本文中有两种类型的周期结构。一种是多层板（一维光子晶体），另一种是介质柱的方晶格（二维光子晶体）。采用时域有限差分（FDTD）方法进行数值计算。带阻的频率和空间特性以数值示例的形式示出。
We have analyzed the band-stopping characteristic of non-metal periodic structures for electromagnetic wave in a microwave region. The target frequencies are 2.4 and 5 GHz bands, which are popularly used in wireless LAN in Japan. There are two types of periodic structure in this article. One is the multilayer slab (a 1D photonic crystal) and the other is the square lattice of dielectric columns (a 2D photonic crystal). The finite-difference time-domain (FDTD) method is employed for the numerical calculation. Frequency and spatial characteristics of band-stopping are shown as numerical examples.
