DOI: 10.1016/j.ultramic.2016.11.029
Abstract: The theoretical possibility to use an electron microscope as a spin polarizer is studied. It turns out that a Bessel beam passing a standard magnetic objective lens is intrinsically spin polarized when post-selected on-axis. In… read more here.

DOI: 10.1038/s41598-019-56369-z
Abstract: We report zero-th and high-order acoustic Bessel beams with broad depth-of-field generated using acoustic holograms. While the transverse field distribution of Bessel beams generated using traditional passive methods is correctly described by a Bessel function,… read more here.
