Abstract

A silicon subwavelengh axicon for terahertz beam polarization transforming has been de-signed, fabricated, and investigated by methods of numerical and optical experiments. The research has been performed on a free-electron laser workstation NOVOFEL (Budker Institute of Nuclear Physics of SB RAS, Novosibirsk). Experimental studies have shown the effective polarization conversion performed by the created silicon element.
