The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...
(Phys.org)—David Ruffner and David Grier of New York University have developed a technique for using Bessel beams to draw a particle toward a source. In their paper published in Physical Review ...
SEM is a common microscopy technique for scanning a surface. In SEM, a beam of high-energy electrons is fired from an electron gun towards a sample of interest. The beam of electrons is controlled by ...
