Sub-wavelength annular-slit-assisted superoscillatory lens for longitudinally-polarized super-resolution focusing
A binary metallic superoscillatory lens assisted with annular subwavelength slits is proposed, which generates a longitudinally-polarized super-resolution focal point. The annular slits are designed to selectively transmit radially-polarized light. Simulations using the finite element method show a...
