Continuous numerical aperture properties of a cylindrically polarized light illuminated sub-wavelength annular aperture.
We investigated the process of focusing a radially polarized (RP) light beam through a sub-wavelength annular aperture (SAA). We found that the result was a non-diffraction doughnut-shaped light beamExpand
