摘要:

针对目前广泛关注的集成材料,提出了采用时域有限差分法(FDTD)分析集成材料(有效介电常数为负数)对电磁波的反射和透射特性,并与已有的理论模型和实验数据进行了比较,验证了采用FDTD方法分析集成材料的可行性. 为集成材料的设计及应用提供了理论依据和数值分析方法.

关键词: 集成材料, 负介电常数, 反射和透射特性

Abstract:

A new method based on finite difference time domain (FDTD) method was presented for numeric analyze of the transmission and reflection characteristic of the composite materials with negative effective permittivity. The simulation was compared with the existed theoretic model and other experiment data. The result shows that the feasibility of using FDTD method to analyze the composite materials is validated, and also shows that it is a sample work for the design and application composite materials.

Key words: composite materials, negative permittivity, transmission and reflection characteristic
