- Additional information
- A new and radically different engineering design concept which removes the need to deploy heavy and power hungry motors to steer the beem of a spacecraft antenna was proposed. This wok conducted in collaboration with the Universidad Politécnica de Madrid, the European Space Agency and Merck KGaA, Germany was the first in the world to develop a millimetre wave reflectarray antenna that uses a thin layer of liquid crystals to provide a compact and energy efficient electronic solution that overcomes the major performance limitations in existing spacecraft scanning antenna designs.
