In this article, a 2-D Airy beam is experimentally generated at microwave frequency by using
a simple and thin metasurface composed of a single-layer of square C-shaped …

The dual focus property of focused circularly polarized ring Airy beam (RAB) under the
action of tightly focused lens is demonstrated in this paper. The radiation forces at two foci of …

A polarization insensitive achromatic metalens (PIAML) was designed to realize a high NA
of 0.5 and uniform focusing efficiency in the visible range based on a double layer structure …

The functionality of most of the metasurfaces that have been investigated so far, especially in
illuminations with arbitrarily linearly polarized incident light, are restricted to x-or y-polarized …

We study the propagation dynamics of Janus vortex wave under the action of a focusing lens
based upon the formula of focused circular vortex Airy beams. Two dark foci would be …

Optical metasurfaces with versatile focal properties have great importance and adaptability
in photonic systems and potential applications. The unique capability of the ultra-compact …

In the field of metasurface-based light focusing, both convex metalenses with parabolic
phase profile and autofocused Airy (AFA) beams play essential roles. AFA beam generation …

Axicons with the ability to convert Gaussian beams into non-diffracting Bessel beams are
well-known in the field of light focusing for their large depth-of-focus. In this paper, we …

In the context of light focusing, converging Airy beams play an essential role. The two Airy
beams that are commonly used in the literature for autofocusing of the Airy beams are mirror …

To focus the incident light, both convex metalenses with hyperbolic phase profile and
autofocused Airy (AFA) beams are widely used. To obtain AFA-based bifocal metalenses …
