Visual search is a common practice conducted countless times every day, and one important aspect of visual search is that multiple targets can appear in a single search array. For example, an X-ray image of airport luggage could contain both a water bottle and a gun. Searchers are more likely to miss additional targets after locating a first target in multiple-target searches, which presents a ...

This review is written to introduce infrared photon detectors based on solution-processable semiconductors. A new generation of have been reported in the past few decades colloidal quantum dots, two-dimensional materials, organics semiconductors, and perovskites. These materials offer sensitivity within spectral regions advantages ease fabrication at low temperature, tunable properties, mechani...

The commercial availability of low-cost millimeterwave (mmWave) communication and radar devices is starting to improve the adoption such technologies in consumer markets, paving way for large-scale dense deployments fifthgeneration (5G)-and-beyond as well 6G networks. At same time, pervasive mmWave access will enable device localization device-free sensing with unprecedented accuracy, especiall...
