基于变换光学方法,提出了金属板透视装置,导出了其介电常数和磁导率分布,并采用有限元分析软件COMSOL进行了证实。仿真了TE波和线电流源激励下的透视特性,并详细讨论了透视装置互补区和恢复区的相对位置及其损耗对透视特性的影响,结果表明:TE波和线电流源激励下该装置均有透视功能,并且其透视特性不受互补区和恢复区相对位置变化的影响;电磁波透过金属板时,在金属板与互补区交界面上形成强场区,相对损耗小于10-7对强场区电场强度和相位无影响;当相对损耗小于10-3时,电磁波仍能够完全透过金属板。
Based on the transformation optics method, a metal plate see-through device was proposed, and its dielectric constant and permeability distribution were derived. The finite element analysis software COMSOL was used to verify the results. The simulation of the TE wave and line current source excitation under the perspective of the perspective and detailed discussion of the perspective of the complementary devices and recovery area relative position and loss of the perspective of the impact of the characteristics of the results show that: TE wave and line current source excitation device Both have the perspective function, and its perspective characteristics are not affected by the relative position of the complementary region and the recovery region. When electromagnetic waves are transmitted through the metal plate, a strong field region is formed at the interface of the metal plate and the complementary region with the relative loss less than 10-7 Strong field electric field strength and phase no effect; when the relative loss is less than 10-3, the electromagnetic wave can still be completely through the metal plate.
