In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

Dielectrics represent a new frontier for surface-enhanced Raman scattering. They can serve
as either a complement or an alternative to conventional, metal-based SERS, offering key …

Terahertz (THz) technology has experienced rapid development in the past two decades.
Growing numbers of interdisciplinary applications are emerging, including materials …

We investigated the generation of terahertz (THz) surface magnetoplasmons (SMPs) over a
rippled surface of magnetized n-type semiconductor (n-InSb) by using the nonlinear mixing …

The first objective of this article is to explain what surface plasmons and surface plasmon
polaritons are. The term surface plasmons (SPs) was first coined in the middle of the 20th …

We experimentally demonstrate a three-dimensional plasmonic terahertz waveguide by
lithographically patterning an array of sub-wavelength pillars on a silicon substrate. Doped …

We proposed a tunable multiresonance graphene sensor consisting of a graphene disk and
three non-overlapping graphene rings on a dielectric substrate. Compared to the previous …

Nonlinear optical (NLO) single crystals with high quality are the pillars for the development
of new devices that fulfil the demands of society. Nowadays, NLO single crystals are very …

Graphene has been recently proposed as a promising alternative to support surface
plasmons with its superior performances in terahertz and mid-infrared range. Here, we …

Metamaterial devices (metadevices) have been developed in progress aiming to generate
extraordinary performance over traditional devices in the (sub-) terahertz (THz) domain, and …
