AP2 THz System Concepts & Experimental Preliminary Investigations

Lead: Universität Duisburg-Essen, Prof. Czylwik

In all THz systems, the achievable power density of the signal at the measurement or reception location is a critical parameter. Despite significant progress in the past, the transmit powers achievable with semiconductor devices at 1 THz are still below 100 µW [SED/2022]. Therefore, highly focusing antennas are required, which may need to be rapidly steered depending on the application. This necessitates beamforming techniques that can be implemented both actively through electronically controlled fields from THz emitters and passively through mechanically adjustable antennas, as well as through micro-mechanically or electronically controlled reflector arrays.


The goal of AP2 is to enhance the performance of established system concepts, thereby enabling their use in new applications, as well as to develop new system concepts that open up new applications. Miniaturization is of great importance, especially for mobile or portable applications, as is integration, so that cost-effective mass-produced products can be envisioned in the future.
