Abstract
A compact transducer system includes both an antenna subsystem and an optical transducer subsystem. The antenna subsystem may include multiple radio frequency (RF) radiating elements disposed adjacent to a ground plane. The ground plane may also serve as an optical reflector within an optical path of the optical transducer subsystem. A secondary reflector may also be provided within the optical path of the optical transducer subsystem. The secondary reflector may be formed of dielectric material (e.g., meta-material) in some embodiments to prevent undesired coupling with RF circuitry.
