Spaser is an acronym for surface plasmon amplification by stimulated emission of radiation.
A spaser is effectively a nanoscale laser with subwavelength dimensions and a low-Q …

A subwavelength water metamaterial is proposed and analyzed for ultra-broadband perfect
absorption at microwave frequencies. We experimentally demonstrate that this metamaterial …

A fundamental manifestation of wave scattering in a disordered medium is the highly
complex intensity pattern the waves acquire due to multi-path interference. Here we show …

A terahertz fishnet metamaterial, consisting of a gallium arsenide substrate sandwiched
between multi-layer graphene-dielectric composites, is theoretically studied. Detailed …

Nanooptics which describes the interaction of light with matter at the nanoscale, is a topic of
great fundamental interest to physicists and engineers and allows the direct observation of …

The inception of the plasmonic laser or spaser (surface plasmon amplification by stimulated
emission of radiation) concept in 2003 provides a solution for overcoming the diffraction limit …

Recent progress in manipulating individual quantum systems has led to the development of
quantum thermal transistors, which control the thermal conductivity between two of its …
