用保角变换光学控制电磁表面波

Controlling Electromagnetic Surface Waves with Conformal Transformation Optics

Xiaoyu Zhao, Hong Deng, Xiaoke Gao, Xikui Ma, Tianyu Dong

摘要:

应用变换光学来开发有趣的电磁器件可以在准共形和/或共形映射的帮助下产生弱各向异性或各向同性介质,而不是由一般映射产生的强各向异性介质;然而,它通常限于二维应用。通过解决嵌入在三维空间中的两个流形之间的共形映射,我们证明了电磁表面波可以被控制,而不引入奇异性和各向异性的设备参数。利用富有成效的曲面共形参数化方法,可以得到任意边界光滑流形之间的近完美共形映射。插图的伪装和幻想,包括表面Luneburg和伊顿透镜和黑洞表面波,提供。我们的工作使微波和光波长的表面波操纵更近了一步。

英文摘要:

The application of transformation optics to the development of intriguing electromagnetic devices can produce weakly anisotropic or isotropic media with the assistance of quasi-conformal and/or conformal mapping, as opposed to the strongly anisotropic media produced by general mappings; however, it is typically limited to two-dimensional applications. By addressing the conformal mapping between two manifolds embedded in three-dimensional space, we demonstrate that electromagnetic surface waves can be controlled without introducing singularity and anisotropy into the device parameters. Using fruitful surface conformal parameterization methods, a near-perfect conformal mapping between smooth manifolds with arbitrary boundaries can be obtained. Illustrations of cloaking and illusions, including surface Luneburg and Eaton lenses and black holes for surface waves, are provided. Our work brings the manipulation of surface waves at microwave and optical wavelengths one step closer.
