Nanostructured surfaces with designed optical functionalities, such as metasurfaces, allow
efficient harvesting of light at the nanoscale, enhancing light–matter interactions for a wide …

Terahertz metamaterial sensing (TMS) is a new interdisciplinary technology. A TMS system
employs terahertz waves as the pum** source, these then interact with the sample and …

It is well established that for symmetry‐protected bound states in the continuum (BICs),
introducing the broken geometry symmetry in a dielectric metasurface transforms such a BIC …

Metasurfaces are ushering in an era of multifunctional control over optical wavefronts
realized with ultrathin planarized devices. Recent advances have been enabling …

We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic)
meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising …

Metasurfaces, a two-dimensional (2D) form of metamaterials constituted by planar meta-
atoms, exhibit exotic abilities to tailor electromagnetic (EM) waves freely. Over the past …

A bound state in the continuum (BIC) is a nonradiating state of light embedded in the
continuum of propagating modes providing drastic enhancement of the electromagnetic field …

Symmetry-protected bound states in the continuum (BICs) are nonradiative states with
infinite lifetime and perfect confinement of energy even though lying in the radiation …

Nonradiating sources of energy have traditionally been studied in quantum mechanics and
astrophysics but have received very little attention in the photonics community. This situation …

This work reviews fundamentals and the recent state-of-art achievements in the field of
plasmonic biosensing based terahertz (THz) spectroscopy. Being nonpoisonous and …
