摘要

通过计算损耗型单负材料双层异质结构中的透射、反射和吸收随损耗系数的变化

对单负材料双层异质结构基于损耗的光学性质调控进行了研究。首先

对损耗型单负材料单层结构的透射行为进行了计算

给出了单层结构随损耗系数增大的非单调透射的变化图像。接着

计算了损耗型单负材料双层异质结构中的透射、反射和吸收随损耗系数的变化曲线

并分析了不同频率下透射与损耗系数之间的关系。研究结果表明

在远离隧穿频率处

随损耗系数的逐渐增大

异质结的透射呈现出先减小后增大的变化。计算的电磁场强度分布图像表明

双层异质结中透射与损耗系数之间为非单调关系

起源于损耗型单负材料界面处的反常场局域效应

即随着损耗系数的增大

场局域先减弱后增强。

Abstract

The effects of material loss on light propagation in heterostructure comprising of two single-negative layers were studied

with the aim of light manipulation based on loss. Firstly

transmission of a single-negative layer was calculated

and the variation of the non-monotonic transmission with the dissipation coefficient in the structure was given. Then

the relationships of the transmission

reflection and absorption with the dissipation coefficient in the double layer heterostructure of the two single-negative materials were dicussed

and the variation of the transmission at different frequency was analyzed. Finally

the distribution of the electromagnetic field intensity was shown in order to explain the anomalous transmission phenomenon with the dissipation coefficient. The results illuminate that the anomalous nonmonotonic transmission behavior with the increasing of dissipation coefficient remains in the double layer heterostructure of the single-negative materials

only at the far from tunneling frequencies. This reason is the anomalous localized fields in the interface between two different single-negative materials.
