Abstract Surface-enhanced infrared spectroscopy is an important technique for improving the signal-to-noise ratio of spectroscopic material identification measurements in the mid-infrared fingerprinting region. However, the lower bound of the fingerp

This work presents a compact metafilm, which provides frequency-selective reflection and is based on subwavelength metallic discs lined using μ -negative and near-zero (MNNZ) metamaterial liners. It is shown that such particles undergo resonance at

The widespread offering of online engineering classes has not been without its share of controversy [1] – [7] . There are those who question the pedagogic quality of courses made freely available through video-sharing platforms like YouTube, which

Emerging electromagnetic inverse design methods have pushed nanofabrication methods to their limits to extract maximum performance from plasmonic aperture-based metasurfaces. Using plasmonic metamaterial-lined apertures as an example, we demonstrate

Meeting the evolving demands of plasmonics research requires increasingly precise control over surface plasmon properties, which necessitates extremely fine nanopatterning, complex geometries, and/or long-range order. Nanoplasmonic metasurfaces are r

This article presents a highly compact metafilm structure with two closely spaced and independently controlled shielding bands. The constituent unit cell is a composite of two different single-band metafilm unit cells realized by the application of a

We demonstrate the design and nanofabrication of a new class of metasurface based on arrays of densely packed subwavelength apertures made to resonate through the inclusion of nanostructured plasmonic epsilon-negative and near-zero metamaterials. The

We report a novel resonant metasurface (MTS) based on mu-negative and near-zero (MNNZ) metamaterial (MTM)-lined disks for improved surface-enhanced mid-infrared spectroscopy, which relies on the strong electric-field enhancement near plasmonic metals

Many proposed visible-light metasurface designs are limited in their ability to confine light on a subwavelength scale, which reduces their maximum efficiency due to discretization errors. Plasmonic metasurfaces show great promise in this regard, as
