| 摘 要： | 针对广泛关注的左手材料(负折射率媒质),对电磁波穿过左手材料(Left-handedm aterial)构成的平行板时的传播特性做了理论分析;采用FDTD方法对正弦电磁波穿过了LHM的平行板的传播过程进行了数值建模,数值模拟的结果证明了正弦电磁波在穿过平板状的左手材料,会有类似一般凸透镜的聚光效果,以及负折射特性,为LHM的广泛应用提供了理论基础.

| Abstract: | The increasing interest in the left-handed metamateterials(LHM) requires a formulation capable of a full analysis of wave propagation in such materials.FDTD method is used to simulate the electromagnetic wave propagation around and inside the 2D negative refractive index material slab.A parallel-sided slab of the medium illuminated with a monochromatic source is shown to produce a focus on the far side.Therefore,the left-handed metamateterials(LHM) that formed by a group of man-made materials have been widely used. |
