TLDR
In this paper, the authors study how control of illumination conditions allows manipulation of nanoscale optical fields near plasmonic metasurface patches and reveal how to construct complete bases and perform compressed sensing.Abstract:
We study how control of illumination conditions allows manipulation of nanoscale optical fields near plasmonic metasurface patches. Discrete dipole modelling reveals how we can construct complete bases and perform compressed sensing.read more

TL;DR: In this paper, the location of a nanoscale object is transduced into the transducer's far-field optical response by perturbing the near-field environment of a metasurface transducers.

Optical stethoscopy: Image recording with resolution λ/20
TL;DR: In this paper, an extremely narrow aperture along a test object equipped with fine-line structures was used to demonstrate a resolving power of at least λ/20 which is to be compared with the values of λ 2.3 obtainable in conventional optical microscopy.

A performance comparison of measurement matrices in compressive sensing
TL;DR: The foundation of compressive sensing is explained and the process of measurement is highlighted by reviewing the existing measurement matrices, and a 3‐level classification is provided and the results show that the Circulant, Toeplitz, and Hadamard matrices outperform the other measurementMatrices.
