Over the past few decades, significant attention has been paid to the biomedical
applications of terahertz (THz) technology. Nowadays, THz spectroscopy and imaging have …

During the last decade, new unusual physical phenomena have been discovered in
studying the optics of dielectric mesoscale particles of an arbitrary three-dimensional shape …

This review highlights recent and novel trends focused on metallic (plasmonic) and dielectric
metasurfaces in photoconductive terahertz (THz) devices. We demonstrate the great …

In this Letter, we report the experimental observations of a tunable curved photonic nanojet
(photonic hook) generated by a 5 µm polydimethylsiloxane microcylinder deposited on a …

Unique effects of terahertz (THz)-wave–matter interaction push rapid progress in THz
optoelectronics aimed at bridging the problematic THz gap. However, majority of modern …

Sapphire shaped crystals are considered as a favorable material platform of the terahertz
(THz) waveguide and fiber optics. Unique physical properties of sapphire, along with …

The notion of controlling light has a very long history. The biblical account of the formation of
the universe begins as “Let there be light!”[1]. Writing circa 300 BCE, Euclid introduced the …

Recently, a type of curved light beams, photonic hooks (PHs), was theoretically predicted
and experimentally observed. The production of photonic hook (PH) is due to the breaking of …

When light propagates through the edge or middle part of a microparticle's incoming
interface, there is a basic rule that light converges and diverges rapidly or slowly at the …
