Abstract: Spatial light modulators and associated methods are described. In one embodiment, a spatial light modulator includes a photonic integrated circuit configured for emitting a plurality of light beams as a first waveform by a plurality of pixels. The light beams are individually controllable. The spatial light modulator also includes a meta-optic having a plurality of nanostructures configured for receiving the first waveform and aggregating the plurality of light beams as a second waveform at a surface of the meta-optic. The spatial light modulator also includes an aperture array configured for converting the second waveform into a third waveform, where the third waveform is smaller than the second waveform.

Abstract: Examples described herein include devices and methods that may facilitate interoperability between backscatter devices and wireless communication devices. For example, backscatter devices and methods for backscattering are described that provide a transmitted backscattered signal formatted in accordance with a wireless communication protocol (e.g. Bluetooth Low Energy, WiFi, IEEE 802.11, or IEEE 802.15.4). Such communication may reduce or eliminate any modifications required to wireless communication devices necessary to receive and decode backscattered signals.

Abstract: Examples of active millimeter-wave imaging systems are described which may utilize modulation schemes to provide illumination signals. The use of modulation techniques may allow for the use of direct-conversion receivers while retaining an ability to separate desired received signal from self-jamming and/or DC offset signal(s) generated by the direct-conversion receivers. In some examples, modulation schemes include the use of balanced orthogonal codes which may support MIMO or massive MIMO imaging systems.

Abstract: Examples of receivers and receiver techniques are described herein. An example system may include a carrier source that may provide a wireless carrier signal and a wireless communication device, separate from the carrier source. The wireless communication device may provide a wireless communication signal containing data. A receiver may include an antenna positioned to receive the wireless carrier signal and the wireless communication signal, a two-port mixer coupled to the antenna and configured to mix the wireless carrier signal and the wireless communication signal to provide an intermediate frequency signal, and a demodulator configured to extract, at least in part, the data from the intermediate frequency signal.

Abstract: Examples of imaging systems are described herein which may implement microwave or millimeter wave imaging systems. Examples described may implement partitioned inverse techniques which may construct and invert a measurement matrix to be used to provide multiple estimates of reflectivity values associated with a scene. The processing may be partitioned in accordance with a relative position of the antenna system and/or a particular beamwidth of an antenna. Examples described herein may perform an enhanced resolution mode of imaging which may steer beams at multiple angles for each measurement position.
