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 …

Advances in metamaterials have offered the opportunity of engineering electromagnetic
properties beyond the limits of natural materials. A typical example is “spoof” surface …

In this paper, we present a simple design of six-band terahertz (THz) perfect metasurface
absorber (PMSA) composed of a single circular-split-ring (CSR) structure placed over a …

We present a wide-angle tunable dual-band terahertz (THz) metamaterial absorber (MMA)
based on square graphene patch (SGP). This MMA is a simple periodic array, consisting of a …

The plasmonic waveguide made of uniform corrugated metallic strip can support and guide
spoof surface plasmon polaritons (SSPPs) with high confinements. Here, we propose …

Along with the rapid development of micro/nanofabrication technology, the past few decades
have seen the flourishing emergence of subwavelength-structured materials and interfaces …

Localized surface plasmons (LSPs) are localized oscillations of free electrons in metal
nanoparticles at optical frequencies. Confined mode profiles and near‐field enhancements …

Since 2004, my group at Southeast University has been carrying out research into
microwave metamaterials, which are classified into three catagories: metamaterials based …

We experimentally observe the excitation of dark multipolar spoof localized surface plasmon
resonances in a hybrid structure consisting of a corrugated metallic disk coupled with a C …
