Abstract
Systems, methods, and apparatus are described to provide a large emittance angle and a large beamforming aperture for radiation emitted by a relatively small transmit aperture. For example, a diffractive concentrator structure can provide a large emittance angle and a large beamforming aperture for radiation emitted by a small transmit aperture and delivered to a larger exit aperture.
