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 …

Surface plasmon polaritons (SPPs) are localized surface electromagnetic waves that
propagate along the interface between a metal and a dielectric. Owing to their inherent …

This paper presents a theoretical model and validates experimentally the microwave slow-
wave transmission line (SW-TL) based on spoof surface plasmon (SSP) modes. Equivalent …

Frequency-controlled broadband and broad-angle beam scanning is proposed using a
circular-patch array fed by planar spoof surface plasmon polaritons (SPPs). Here, a row of …

Metamaterials offer a new approach to create surface coatings with highly customizable
electromagnetic absorption from the microwave to the optical regimes. Thus far, efficient …

We propose a planar plasmonic metamaterial on thin corrugated metal films in microwave
and terahertz frequencies. From theoretical simulation and experiment, we show that spoof …

Photonic topological valley kink states have become a significant research frontier with a
plethora of applications. Unlike the guided modes with adjustable widths in conventional …

Graphene is widely known for its anomalously strong broadband optical absorptivity of 2.3%
that enables seeing its single-atom layer with the naked eye. However, in the mid-infrared …

Surface plasmons have found a broad range of applications in photonic devices at visible
and near-infrared wavelengths. In contrast, longer-wavelength surface electromagnetic …
