Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

We numerically and experimentally study the autofocusing and self-healing of partially
blocked circular Airy derivative beams (CADBs). The CADB consists of multiple rings, and …

Exploring and taming the diffraction phenomena and divergence of light are foundational to
enhancing comprehension of nature and developing photonic technologies. Despite the …

In this article, two 3-D-printed all-dielectric meta-structures that can produce diffraction-free
self-acceleration beams with different transverse intensity profiles are proposed in the …

We investigate both analytically and numerically the propagation dynamic of on-axis and off-
axis cosine-Gaussian (CG) beams in a linear medium with quadratic external potential. CG …

Abstract Description of structured beams in spherical coordinates is critical in studying the
interaction between beams and spherical particles. The work extends the cylindrical wave …

We provide a simple analysis based on ray optics and Dirac notation for 1D (one-
dimensional) and 2D (two-dimensional) non-diffracting modes in the cosine profile, which …

Metasurfaces with linear phase gradients can redirect light beams. Controlling both phase
and amplitude of a metasurface is proposed to extend Snell's law to the realm of complex …

THz radiation has assumed great importance thanks to the efforts in the development of
technological tools used in this versatile band of the electromagnetic spectrum. Here, we …
