Here, we have reviewed some typical plasmonic structures based on Archimedes' spiral
(AS) architectures, which can produce polarization-sensitive focusing phenomenon and …

Focusing on control and manipulation of plasmons at nanometer dimensions,
nanoplasmonics combines the strength of electronics and photonics, and is predicted to …

We have designed a novel plasmonic lens for the circular polarization analyzer based on
the combined coaxial Archimedes' spiral structure which is composed of a Archimedes' …

A miniature, simplified and planar plasmonic lens based on the circular array of nano-
pinholes for on-axis beaming has been proposed and investigated systematically in the …

For the miniaturization of optical devices, surface plasmon polaritons (SPPs) have been
widely utilized due to their outstanding confinement and field‐enhancement characteristics …

A tip-enhanced Raman spectroscopy (TERS) based on plasmonic lens (PL) excitation is

Strong polarization dependence in the optical transmission through a bull's eye with a
central elliptical aperture in a thin Au film is analyzed numerically by finite difference time …

A chiral plasmonic lens (CPL) suitable for circularly polarized light is proposed; it consists of
multiple concentric grooves surrounded by two Archimedes-spiral distributed arrays of …

We propose a switching method for optical beaming generated from a metal slit surrounded
by surface gratings. The principle of the method is based on the interference of diffracted …

We propose a scheme for directional beam switching from line-envelope tilted nanoslit array
surrounded by gratings. The line-envelope nanoslit array composed of double arrays of …
