In solid state physics, a bandgap (BG) refers to a range of energies where no electronic
states can exist. This concept was extended to classical waves, spawning the entire fields of …

The terahertz (THz) wave is at the intersection between photonics and electronics in the
electromagnetic spectrum. Since the vibration mode of many biomedical molecules and the …

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 …

Artificially engineered metamaterials are now demonstrating unprecedented
electromagnetic properties that cannot be obtained with naturally occurring materials. In …

Increasing attention on metamaterials has been paid due to their exciting physical behaviors
and potential applications. While most of such artificial material structures developed so far …

A new type of cloak is discussed: one that gives all cloaked objects the appearance of a flat
conducting sheet. It has the advantage that none of the parameters of the cloak is singular …

In this paper, an improved algorithm for extracting the effective constitutive parameters of a
metamaterial is derived. The procedure invokes the Kramers–Kronig relations to ensure the …

A form of optical circuitry is overviewed in which a tapestry of subwavelength nanometer-
scale metamaterial structures and nanoparticles may provide a mechanism for tailoring …

Theory and Phenomena of Metamaterials offers an in-depth look at the theoretical
background and basic properties of electromagnetic artificial materials, often called …

PERSPECTIVES wavelength replace the atoms and molecules of a conventional material,
scientists can circumvent this limitation. Metamaterials can be designed to exhibit both …
