Dielectric microelements with circular symmetry have shown interesting optical properties:
photonic nanojets (PNJs) and whispering gallery modes (WGMs). They can confine light …

Metasurfaces, composed of two-dimensional nanostructures, exhibit remarkable capabilities
in shaping wavefronts, encompassing phase, amplitude, and polarization. This unique …

A truncated Ti and Si cones metasurface has been proposed for wide-band solar absorber
(WSA), which produced a high average absorption of 94.7% in the spectral region from 500 …

We studied the characteristics of photonic nanojets formed by dielectric microcylinders over
the visible spectrum using FDTD numerical simulations. We varied a wide range of tuning …

The last two decades have witnessed a dramatic increase in research on low‐dimensional
material with exceptional optoelectronic properties. While low‐dimensional materials offer …

In the past decades, metamaterial light absorbers have attracted tremendous attention due
to their impressive absorption efficiency and significant potential for multiple kinds of …

Abstract Photonic Nanojets (PNJs) have attracted considerable research attention in the
fields of super-resolution optical microscopy, nano-photolithography, and single molecule …

We experimentally report the geometric effect on photonic nanojet generated by dielectric
microcylinders with non-cylindrical cross-sections. The non-cylindrical cross-sections …

We numerically investigate the generation of photonic nanojets (PNJs) and the excitation of
whispering gallery modes (WGMs) supported by both smooth and corrugated dielectric …
