We present a quasi-crystal metasurface that can simultaneously work as efficient cross-
polarizer and circular polarizer for wide range of frequencies. The quasi-crystal technique …

A class of metasurfaces for underwater sound absorption, based on a design principle that
maximizes thermoviscous loss, is presented. When a sound meets a solid surface, it leaves …

The Fano resonance has been a familiar and important feature in atomic and molecular
physics for more than half a century. Typically, the combination of a discrete state with one or …

Lasing is a well-established field in optics with several applications. Yet, having lasing or
huge amplification in other wave systems remains an elusive goal. Here, we utilize the …

We give an analytical and experimental demonstration of the possibility to realize a simple
photonic demultiplexer based on electromagnetically induced transparency resonances …

The classical electromagnetic (EM) and acoustic waves interact with metamaterials in
interestingly resembling manner. A robust technique is described to retrieve effective …

Sound waves are sensitive to environmental perturbation effects and therefore offer great
potential for non-invasive sensing of background temperature, pressure or bio-chemical …

A metascreen absorber composed of plasmonic nan-odisk array is used to absorb incident
radiation at optical frequencies. The conventional Nobel metals such as gold and silver are …

The purpose of this talk is to report on the omnidirectional sound screening of an acoustic
metamaterials based on local resonances, which can enable the emergence of concrete …
