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 …

A planar terahertz metamaterial sensor consisting of a corrugated metal stripe perforated by
three rectangular grooves is proposed and investigated numerically. Due to the formation of …

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

The rapid developments in nanotechnology and plasmonics allow the manipulation of light
at nanometer scales, such as light propagation and resonances. Differing from the …

A novel defect‐induced planar meta‐atom that supports multiple Fano resonances in a
defective corrugated metallic disk (CMD) structure is proposed. Numerical and experimental …

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 …

Ultra-wideband spoof surface plasmon polaritons (SSPPs) based on compact balanced
coplanar stripline (CPS) waveguides are proposed. Compared with the conventional CPS …

By directly incorporating a sub-wavelength amplifier chip into the spoof plasmonic resonator,
the quality (Q) factor of the original passive resonator has been significantly increased by …

We propose a compact combined system which supports compound spoof surface
resonances due to the coupling between spoof surface plasmon polaritons (SPPs) and …
