Shaping symmetric Airy beam through binary amplitude …
WebThe symmetric Airy beam exhibits peculiar features. It propagates at initial stages with a single central lobe that autofocuses and then collapses immediately behind the autofocus. Then, the beam splits into two specular off-axis parabolic lobes like those corresponding to two Airy beams accelerating in opposite directions. WebApr 1, 2024 · The Symmetric Airy beams (SABs) originate from the symmetry spectral cubic phase of the traditional Airy beams. In 2024, researchers introduced a rectangular frame … WebA symmetric Airy vortex beam can be generated by modulating a Gaussian beam imposed on an improved phase pattern, where helical phase factor is introduced in symmetric cubic phase. The experimental results and numerical simulations demonstrate that such beams possess autofocusing characteristic and have a dark core owing to on-axis vortex. standard bank funeral policy contact details
