We analyze the propagation dynamics of radially polarized symmetric Airy beams (R-SABs) in a (2+1)-dimensional optical system with fractional diffraction, modeled by Schrödinger equation (FSE) characterized Lévy index, ?. The autofocusing effect featured such becomes stronger, while focal length shorter, increase intrinsic vorticity on is considered too. Then, ability R-SABs to capture nano-par...

Abstract THz-based technologies and research applications have seen a rapid increment in recent period together with the development of novel radiation sources based both on relativistic electrons laser techniques. In this framework, laser-induced plasma filament plays an important role generating intense broadband THz radiation. Although many attentions been paid to emission from two-color fil...
