利用波矢滤波超表面实现超衍射成像
Super diffraction imaging with wave vector selective metasurface
摘要
Abstract
Super diffraction imaging has been a research hotspot for a long time. We realize the super diffraction imaging with a metasurface structure, which is consisted of asymmetrically split rings. Based on the wave vector selectivity of the metasurface, radiation can be transmitted through it only in a narrow range of the incident angular. The metasurface acts as a high frequency spatial filter, reduces the diffraction effect, and obtains the super diffraction resolution. Numerical simulation results demonstrate the validity of this method.关键词
