Description
Summary:This work is focused on electromagnetic scattering of PEC objects by collimated Bessel beams, especially for upcoming imaging applications, and on design criteria for innovative Bessel beam launchers at microwaves and millimeter waves. Numerical examples are obtained by exploiting the developed analytical model for scattering, and finally an example of Bessel beam launcher obtained by an equivalent surface impedance on a planar aperture (i.e., building block for metasurface synthesis) is shown.
