TL;DR: In this article, the volume of a transformation optics (TO) device is divided into flat metamaterial layers, and these layers can be readily implemented by standard fabrication and stacking techniques, for the specific example of a two-dimensional, omnidirectional "invisibility cloak" and quantify its performance using the total scattering cross section.

TL;DR: In this paper, Discrete Dipole Approximation (DDA) is used as a simulation tool for predicting the electromagnetic properties of one dimensional metasurface antennas and slotted waveguide antennas.

TL;DR: Pokrovsky and Efros as discussed by the authors made a comment on the letter by A. L. Pokrovsy and A. Ebros, Phys. Rev. 89, 093901 (2002).

TL;DR: The experimental results show that broadband light can be controlled and redirected in a volume of >105λ × 105λ × 103λ, which enables natural light to be processed directly by metamaterial-based optical devices without any additional coupling components.

TL;DR: This article presents a model for waveguide-backed metasurface antennas fed by one or more coaxial ports and compute key antenna parameters using the model, including the analytic model of a coaxial port, and proposes an efficient method to compute the input impedance of a metAsurface, enabling the calculation of gain and efficiency.
