Metalenses offer significant advantages over classical lenses by allowing compactness and enhancing functionality of optical systems. In this project, the student will design, numerically simulate, and fabricate metalenses operating in the 0.1–1 THz frequency range. Simulations will be performed using Comsol Multiphysics, while fabrication methods will include 3D printing and molding. The work will be conducted at Lepto GmbH, a spin-off company of Empa in Dübendorf.

THz radiationlies between the microwave and infrared regions of the electromagnetic spectrum. THz radiation has unique properties such as non-ionizing interaction with matter, penetration of many non-conductive materials, and sensitivity to molecular vibrations. This makes it ideal for imaging, spectroscopy, and sensing. Importantly, THz frequencies are emerging as a key enabler for next-generation high-speed telecommunications (6G), offering ultra-broadband data transfer and novel satellite communication possibilities.
