| 摘 要： | 在导电和非导电情况下 ,对 1 /3Cantor分形结构相对应的周期分层介质的反射谱进行了分析计算 ,发现周期分层介质与分形介质的反射谱具有相同规律和相似的形状 .非导电介质的反射谱具有周期性和自相似性 ,导电介质的反射谱不具有周期性 ,但是 ,当频率高于某一值时 ,其反射谱就又具有了明显的周期性 .

| Abstract: | The electromagnetic reflection properties of conducting and non-conducting periodic layered medium corresponding to 1/3 Cantor fractal medium are discussed in this paper, It is found that the reflection spectrums of periodic layered medium and Cantor fractal medium have the same properties and similar shape. The reflection spectrum of non-conducting layered medium is periodic and self-similar, and that of conducting layered medium is not periodic as a whole, but when the frequency is higher than a value, it is also periodic. |
