Biosensors have been designed and developed for detecting biomarkers, biomolecules,
proteins, enzymes, organisms, and various types of bacterial and viral diseases since the …

Metamaterials, artificially constructed structures that mimic lattices in natural materials, have
made numerous contributions to the development of unconventional optical devices. With an …

Metamaterials can possess extraordinary properties not readily available in nature. While
most of the early metamaterials had narrow frequency bandwidth of operation, many recent …

Optical activity (polarization rotation of light) is one of the most desired features of chiral
media, as it is important for many polarization‐related applications. However, in the THz …

Multifunctional polarization controlling plays an important role in modern photonics, but their
designs toward broad bandwidths and high efficiencies are still rather challenging. Here, by …

The new paradigm was introduced for achieving excellent electromagnetic (EM) waves
absorption through multi-layer superimposed quasiperiodic-metamaterials, which were …

A transmissive frequency-reconfigurable cross-pola-rization conversion surface is
presented. First, two static cross-polarization conversion unit cells are proposed. Results …

Maintaining the surface transparency of protective covers using transparent heaters in
extreme weather is imperative for enhancing safety in autonomous driving. However …

The active manipulation of polarization state is of fundamental importance to functional
devices integrated in modern terahertz (THz) systems. The emerging chiral metamaterials …

We study theoretically some unique characteristics of surface electromagnetic waves excited
at the interface between two different kinds of general bi-isotropic media, which include …
