Terahertz imaging has found extensive applications in non-destructive testing, security inspection, and other various fields. Intensive research on terahertz systems been executed to pursue high performance resolution depth of field (DOF). However, the with both large DOF have rarely reported. In this paper, a mesoscopic-sized dielectric bilayer sphere-assisted super-resolution method was proposed simultaneously achieve enormously improved extended DOF. Simulation analyses revealed that...

A platform a particle image velocimetry system applied study spray characteristics The effects water pressure air rate, angle, density droplets velocity investigated. surface coefficient (SHTC) was calculated with inverse method based instantaneous plate temperature tested by thermocouples. pressure, jet (nozzle) height, spacing impinging experimental...
The optical force on a perovskite-coated gold nanosphere by polarized Bessel beam is investigated in the generalized Lorenz-Mie theory (GLMT) framework. dielectric function of core described using Drude-Sommerfeld model, and cesium silver bismuth bromide (CABB) considered for coating. axial forces F z are numerically calculated. effects both parameters (half-cone angle α 0 , order l polarization) thickness coating discussed. Numerical results show that peaks can be adjusted changing However,...
Terahertz (THz) spectroscopic detection technology is regarded as an ideal approach for detecting biological substances due to its unique advantages of non-ionization, high penetrability, and fingerprint spectra. However, because the strong absorption THz waves by polar molecules, such water, target dissolved in water challenging. We propose a new method tuning thickness aqueous solution film using superhydrophobic/superhydrophilic (SHB/SHL) surface improve ability obtain spectral...
Terahertz (THz) imaging technology has garnered considerable attention across a range of fields. However, its progress is constrained by the challenge achieving high resolution. The terajet effect, utilizing dielectric structures, emerged for super-resolution THz imaging. Nevertheless, short terajets generated reported structures pose challenges practical matching with experimental setup. This study introduces novel approach employing core-shell microspheres to generate long tunable...
