In this article, a combination of theory and experiment is used to demonstrate that an array of microstrip patches leads to a surface with sharp and tunable emission bands, and the physical mechanisms and locations for various emission peaks are described via both analytical theory and numerical simulations.
Abstract
We demonstrate through a combination of theory and experiment that an array of microstrip patches leads to a surface with sharp and tunable emission bands. The physical mechanisms and locations for various emission peaks are described via both analytical theory and numerical simulations. These predictions agree well with our experimental data, taken on systems designed to emit strongly in the infrared. The main peak, which arises from plasmons trapped under a patch, can be well separated from other spectral structures, narrow in wavelength, but broad in angular distribution.

Broadband focusing flat mirrors based on plasmonic gradient metasurfaces

TL;DR: It is demonstrated that metal-insulator-metal configurations, with the top metal layer consisting of a periodic arrangement of differently sized nanobricks, can be designed to function as broadband focusing flat mirrors and can be extended to realize the radiation focusing in two dimensions as well as other optical functionalities by suitably controlling the phase distribution of reflected light.

Optical antenna thermal emitters

TL;DR: In this paper, the authors show that the thermal emission from a single SiC whisker antenna is attributable to well-defined, size-tunable Mie resonances and derive a fundamental limit on the antenna emittance and argue theoretically that these structures are nearly ideal blackbody antennas.
