Metasurfaces: From microwaves to visible

TL;DR: In this article, the effect of a mushroom-type metasurface on the radiofrequency field distribution inside an MR-scanner was investigated and it was shown that such structures are also applicable to reduce mutual coupling between dipole elements of a body array coil for 7 Tesla MRI (operational frequency equal to 298 MHz).

TL;DR: In this paper, an alternative and complementary approach to constructing negative index materials using atomic transitions of atoms or ions has been proposed, instead of relying on engineered patterns, the idea is to utilize the resonances provided to us by nature.

TL;DR: In this article, a quasi-analytical formulation of spherical metasurfaces using Generalized Sheet Transition Conditions (GSTCs) and Vector Wave Function (VWF) expansion is presented.

TL;DR: In this paper , a predictive method is built to calculate radar cross-section patterns from supercell Floquet simulation, avoiding dealing with heavy simulations, and the proposed model, the optimization outputs and the general results are exposed in details.

TL;DR: In this article, a two-dimensional array of optical resonators with spatially varying phase response and subwavelength separation can imprint phase discontinuities on propagating light as it traverses the interface between two media.

TL;DR: Recent advances at the intersection of plasmonics and photovoltaics are surveyed and an outlook on the future of solar cells based on these principles is offered.

TL;DR: This work fabricate, characterize, and analyze a MM absorber with a slightly lower predicted A(omega) of 96%.

TL;DR: This Review focuses on recent developments on flat, ultrathin optical components dubbed 'metasurfaces' that produce abrupt changes over the scale of the free-space wavelength in the phase, amplitude and/or polarization of a light beam.
