Plasmonic devices, made of apertures or antennas, have played significant roles in
advancing the fields of optics and opto-electronics by offering subwavelength manipulation …

We report experimental behaviors of polarization-dependent, plasmonic-enhanced
molecular fluorescence within isolated bowtie nano-apertures (BNAs) milled in aluminum …

We investigate the light transmission through a nanoaperture in a metal film deposited on a
planar metamaterial. An effect of an anomalously high light transmission (up to 800%) …

A theoretical model is introduced to evaluate the ultimate resolution of plasmonic lithography
using a ridge aperture. The calculated and experimental results of the line array pattern …

Nanofabrication using near-field optical probes is an established technique for rapid
prototyping and automated maskless fabrication of nanostructured devices. In this review …

Based on simultaneous control of the phase and polarization, metallic waveguide
transmiarray antennas (MWTAs) with a single feed are proposed to generate multibeams …

Nanoscale bowtie antenna and bowtie aperture antenna have been shown to generate
strongly enhanced and localized electric fields below the diffraction limit in the optical …

Near-field transducer based on nanoscale optical antenna has been shown to generate
high transmission and strongly localized optical spots well below the diffraction limit. In this …

Bowtie aperture is known to produce subdiffraction-limited optical spot with high intensity. In
this work, we investigate integrating a bowtie aperture with circular grooves to reduce the …

A metallic waveguide transmitarray antenna (MWTA) is proposed to attain dual-band
multibeams with high gain in the terahertz (THz) range, which is realized by independently …
