Radiation pattern analysis for scattering of arbitrary beams by arbitrary particles

Bojian Wei, Shuhong Gong, Renxian Li, Huan Tang et autres

In optical-band antenna systems, scatterers with arbitrary geometric structures are ubiquitous in natural environments. When their dimensions are comparable to the wavelength, the resulting scattering effects can significantly distort radiation characteristics. Different beam types-such as Gaussian, Bessel, and Airy beams-exhibit distinct propagation …

Bessel beam scattering by an infinitely long elliptical cylinder based on the method of lines

Zhe Wang, Renxian Li, Huan Tang, Li Xiao et autres

The scattering of particles by shaped beams has always been a focus of many scholars. Bessel beams, a typical structured light, are widely used due to their unique non-diffracting propagation characteristics and stable transverse size. This study uses the Method of Lines …

Scattering characteristics of a perfect electromagnetic conductor (PEMC) cylinder in a lossy dielectric medium

Fengbei Liu, Renxian Li, Huan Tang, Li Xiao et autres

A comprehensive theoretical understanding of advanced optical materials, such as Perfect Electromagnetic Conductors (PEMCs), is essential for the development of next-generation photonic devices. However, previous analytical models have largely been restricted to idealized, lossless host media, neglecting the dissipative effects present in …

Photonic hook formation by a partially illuminated high-index dielectric particle hemi-immersed in dielectric film

Igor V. Minin, Song Zhou, Huan Tang, Renxian Li et autres

The photonic hook (PH) generated by a partially illuminated high-index dielectric particle hemi-immersed in the dielectric film is investigated. A tunable PH is generated from a cylinder deposited on a dielectric film, and the cylinder is partially illuminated by the placement of …

Far-field scattering characteristics of rotating spherical particles

Huan Tang, Renxian Li, Bing Wei, Shuhong Gong et autres

The scattering of polarized plane waves on a rotating spherical particle, especially the far-field characteristics, is studied based on the “instantaneous rest-frame” hypothesis and Minkowski’s theory. The influence of the rotating angular velocity on the scattering is emphasized and is expressed as …

Resonance scattering generated by rotating bodies

Renxian Li, Huan Tang, Bing Wei, Shuhong Gong et autres

Abstract The scattering of rotating bodies to a polarized plane wave, including the dielectric cylinder and sphere, is studied. The resonance caused by rotation is emphasized. Numerical results prove that the resonance scattering caused by rotation can be realized in the optical …

Photonic jet with tunable focus based on water droplets freezing from the outside in

Oleg Vladilenovich Minin, Zhou Song, Igor V. Minin, Renxian Li et autres

Water droplets are a highly abundant phase-change material to realize tunable optical lenses. We demonstrated for the first time that freezing mesoscale water droplets could be used as a tunable optical lens, such that freezing becomes an asset despite the low absolute …
