During the last decade, new unusual physical phenomena have been discovered in
studying the optics of dielectric mesoscale particles of an arbitrary three-dimensional shape …

The interest to mesoscale dielectric objects, whose effective dimensions are comparable
with the incident radiation wavelength, is caused by their unique ability to modify the spatial …

The photonic nanojet (PNJ) is a narrow high-energy beam that was originally found on the
back side of all-dielectric spherical structures. It is a unique type of energy concentration …

Controlling and manipulating the propagation of surface plasmons has become a field of
intense research given their potential in a wide range of applications, such as plasmonic …

When light propagates through the edge or middle part of a microparticle's incoming
interface, there is a basic rule that light converges and diverges rapidly or slowly at the …

Today the surface plasmon‐polariton (SPP) waves propagating along the curve trajectory
are the only plasmonic beams of the Airy family. Herein, a new class of curved surface …

We propose and study a microstructure based on a dielectric cuboid placed on a thin metal
film that can act as an efficient plasmonic lens allowing the focusing of surface plasmons at …

In this paper we study the excitation of photonic nanojets (PNJ) in 3D dielectric cuboids by
surface plasmons at telecommunication wavelengths. The analysis is done using the …

We demonstrate numerically the feasibility of axial and angular control of the position of a
photonic nanojet (PNJ) by lossless phase-only modulation of a fixed Gaussian beam …

Microsized spheres can focus light into subwavelength spatial domains, a phenomenon
called photonic nanojet. Even though well studied in three-dimensional (3D) configurations …
