Active Metamaterial

Project Objectives

The project "Active Metamaterial" deals with the investigation and prototyping of active metasurfaces based on inductive/capacitive grid or patch fields which will later func­tion as thin lenses and active reflec­tors. The stated goal is to influence either the radiation of integrated antennas or the sensing properties of radar targets.

The following is targeted:

• Design of active and passive metamaterial systems as reflect- and transmit-arrays to enhance, switch or steer emitted mm-wave
• Numerical and analytical development of frequency selective surfaces created from inductive and capacitive arrays in an antenna or sensor systems
• Improvement of antennas using metasurfaces as reflect arrays enabling sub-wavelength resonators
• Switching, focussing or deflecting beams through active transmit arrays which enable electromagnetic wave manipulation
• Direction of arrival estimation applying differently engineered metasurfaces to multiple single antennas
• Verification of the designed structures through full-wave simulations in Ansys HFSS or through fabrication and subsequent over-the-air measurements
• Investigation of potential RF applications in general research fields as e.g. wireless communication, over-the-air measurement techniques, radar, and many more
