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 …

In this article, we present a comprehensive review on recent research progress in design
and fabrication of active tunable metamaterials and devices based on phase transition of VO …

This paper reviews micromachined tunable metamaterials, whereby the tuning capabilities
are based on the mechanical reconfiguration of the lattice and/or the metamaterial element …

We present a simple and versatile approach for fabricating terahertz lenses based on
compression molding of micropowder polymer materials in a tabletop hydraulic press. To …

We suggest a novel possibility for electrically tunable terahertz near-field enhancement in
flatland electronic materials supporting two-dimensional plasmons, including recently …

We investigate field enhancement properties of a tapered parallel plate waveguide for
ultrashort terahertz (THz) pulses. We use two independent methods, air biased coherent …

We studied a well-resolved lens based on planar fully printed resonant-type negative-
refractive-index transmission lines made of complementary split ring resonators. The lens …

We demonstrate metamaterials based on Archimedean spiral arrays that can be used to
create elliptically polarized terahertz (THz) waves from a linearly polarized input wave. The …

Artificially designed modulators that enable a wealth of freedom in manipulating the
terahertz (THz) waves at will are an essential component in THz sources and their …

The fabrication and characterization of over millimeter (mm)-scale Au plasmonic structures
are reported. Fishnet structures of Au are fabricated by the “bottom-up (direct deposition of …
