Metasurfaces have attracted a lot of attention in recent years due to the alternative methods
they provide for the efficient wavefront control and engineering of resonant transmission. We …

Metasurfaces without a mirror symmetry may exhibit chiral electromagnetic response that
differs substantially from any type of polarization transformation. A typical design of chiral …

We demonstrate how to design all-dielectric metasurfaces with a strong axial toroidal
response by arranging two types of nanodisks into asymmetric quadrumer clusters. This …

Magnetoelectric dipole coupling effects in all-dielectric metasurfaces composed of particles
with bianisotropic electromagnetic response are investigated. This bianisotropic response is …

Recently, different experimental methods intended to detect the entangled two-photon
absorption (ETPA) phenomenon in a variety of materials have been reported. The present …

In the electromagnetic wave theory, the term “trapped mode”(also known as a dark mode
and bound state in the continuum) is used to describe modes of a system that are weakly …

We introduce a class of parity-time symmetric elastodynamic metamaterials (Ed-MetaMater)
whose Hermitian counterpart exhibits unfolding (fractal) spectral symmetries. Our study …

Two-photon (TP) three-dimensional solid matrices have potential applications in high
density optical data reading and storage, infrared-pumped visible displays, lasers, etc. Such …

Abstract A quadrupolar D-π-A-π-D oligophenyleneimine with indole moiety as terminal
group (OIC-I) obtained by a green method of mechanosynthesis was obtained. The …

The TM-mode of surface plasmon polaritons (SPPs) can be excited at the interface of a
metal layer and a dielectric medium. The E-mode of the SPPs is excited due to reflection of …
