Paper terahertz lens makes for quick prototyping.

The article discusses the experimental research by researchers at the Warsaw University of Technology of warsaw, Poland and the University of Savoie of Le Bourget du Lac, France on the problems of fabrication process for rapid prototyping. It develops binary phased-based diffracted lenses from a commercially purchased paper to address the fabrication process problem. It suggests that nonparaxial paper diffractive lens with terahertz radiation for quick prototyping.
