Abstract :
We present terahertz lenses made of polymeric compounds which provide a better focusing capability and an increased functionality than state of the art lenses made of pure base polymers. This is achieved by employing mixtures between polypropylene and alumina as well as polypropylene and zinc sulfide which allows for a significant increase of the refractive index of the lens base material.
