摘要

应用并矢量格林函数法完成了球形超透镜的数值模拟,证明了球形超镜的亚波长成像能力.并矢格林函数法是处理电磁场问题的一种系统理论和有效方法,它弥补了坐标变换法的不足.与平板透镜相比,球形超透镜有几个优点,包括有限的横截面,能成放大或者缩小的像,很高的分辨率,进行二维成像等.

In this paper, we carry out the numerical simulation of spherical superlens by the Dyadic Green’s function method, and we prove the sub-wave length imaging capability of spherical superlens. Dyadic Green’s function method is an effective method and a systematic theory of dealing with the problem of electromagnetic fields, which makes up the deficiencies in coordinate transformation method. Compared with the flat lens, the spherical superlens have several advantages, including the finiteness cross-section, and ability in lensing with magnification or demagnification, high resolution, two-dimensional imaging, etc.
