In this paper, we present a brief overview of near-field plates, which are nonperiodic grating-
like surfaces/arrays that can focus electromagnetic field to subwavelength resolutions. The …

When a small radiating or scattering object is placed near a multilayer array of plasmonic
nanospheres, on the other side the optical near field is enhanced due to the excitation of …

This article reviews some of the recent progress made in the field of near-field focusing and
near-field imaging. In particular, it addresses the “meta-screen” that produces a …

A near-field antenna array probe is presented that can perform subwavelength-focused
imaging at a distance of 0.25¿. The array is composed of a centrally fed dipole with open …

A method and apparatus for near-field focusing of an incident wave, over a range of
frequencies from microwaves to optical frequencies, into a sub-wavelength spot having a …

We present the design and experimental demonstration of a magnetic screen, which can
pattern magnetic field into 256 programmable spots of small sub-wavelength dimension. A …

Two-dimensional (2D) subwavelength imaging using a near-field antenna array probe is
demonstrated experimentally at a probe-to-object separation distance of λ/4⁠. Field …

A two-dimensional imaging technique is proposed based on an array of monopole antennas
that produces a near-field subwavelength focal spot. The antennas are designed to produce …

自上世纪60 年代无线能量传输首次成功的实验验证以来, 该技术已成为电子科学与技术多个子
领域的热门研究方向. 近年来, 在物联网, 移动通信, 和新能源汽车等变革式迅猛发展的推动下 …

This thesis presents an investigation on imaging beyond the diffraction limit with
superoscillatory electromagnetic waves. It begins with a survey on sub-diffraction imaging …
