Enhanced transmission of electromagnetic waves through split-ring resonator-shaped apertures [PDF]

, 2011
The design of aperture shape is a promising approach for enhanced transmission through a subwavelength aperture. We designed split-ring-resonator (SRR)-shaped apertures in order to increase the transmission through subwavelength apertures by making use ...

Lensless Imaging by Compressive Sensing

, 2013
In this paper, we propose a lensless compressive imaging architecture. The architecture consists of two components, an aperture assembly and a sensor. No lens is used. The aperture assembly consists of a two dimensional array of aperture elements.
