Abstract

The scattering of a Bessel beam (BB) incident field by a dielectric circular cylinder is here discussed and compared to more standard plane wave (PW) scattering, in such a way to clearly show that the scattering by BBs is more localized than that by PWs. Such an inherent localized scattering process, especially if applied to dense dielectric scatterers, offers new possibilities for imaging techniques at millimeter waves, especially of biological media.
