In the late nineteenth century, Heinrich Hertz demonstrated that the electromagnetic
properties of materials are intimately related to their structure at the subwavelength scale by …

Metamaterials are typically engineered by arranging a set of small scatterers or apertures in
a regular array throughout a region of space, thus obtaining some desirable bulk …

Plasmons describe collective oscillations of electrons. They have a fundamental role in the
dynamic responses of electron systems and form the basis of research into optical …

Using the freedom of design that metamaterials provide, we show how electromagnetic
fields can be redirected at will and propose a design strategy. The conserved fields—electric …

We present the design for an absorbing metamaterial (MM) with near unity absorbance A
(ω). Our structure consists of two MM resonators that couple separately to electric and …

The advent of negative index materials has spawned extensive research into metamaterials
over the past decade. Metamaterials are attractive not only for their exotic electromagnetic …

In this roadmap article, we have focused on the most recent advances in terahertz (THz)
imaging with particular attention paid to the optimization and miniaturization of the THz …

Recently, artificially constructed metamaterials have become of considerable interest,
because these materials can exhibit electromagnetic characteristics unlike those of any …

From theoretical model to experimental realization, the bound state in the continuum (BIC) is
an emerging area of research interest in the last decade. In the initial years, well-established …

One of the most striking phenomena in condensed-matter physics is the quantum Hall effect,
which arises in two-dimensional electron systems,,, subject to a large magnetic field applied …
