Nanohole array as a lens

By Fu Min Huang, Tsung Sheng Kao, Vassili A. Fedotov, Yifang Chen and Nikolay I. Zheludev

Abstract

Here we theoretically demonstrate that a quasi-crystal array of nanoholes in a metal screen can perform the function of a lens: one-to-one imaging of a point source located a few tens of wavelengths away from the array to a point on the other side of the array. A displacement of the point source leads to a linear displacement of the image point. Complex structures composed of multiple point sources can be faithfully imaged with resolutions comparable to those of high numerical aperture lenses
