Polarization Aspects of Near-Field Radiation From Nanoscale Subwavelength Apertures

Not Accessible

Your library or personal account may give you access

Abstract

It is demonstrated that a square nanoaperture can mediate polarized diffraction-limited radiation into nanoscale optical spots with the same polarization. A rectangular nanoaperture can convert linearly-polarized diffraction-limited radiation into circularly and elliptically-polarized nanoscale optical spots.
