Phase retrieval for radar waveform design
Information and Inference: A Journal of the IMAAbstract The ability of a radar to discriminate in both range and Doppler velocity is completely characterized by the ambiguity function (AF) of its transmit waveform. Mathematically, it is obtained by correlating the waveform with its Doppler-shifted and delayed replicas.

Dilution Effect for High‐Performance Multiple‐Component Near‐Infrared Organic Photodetectors
Advanced Science, EarlyView.The dilution effect in multi‐component organic photodetector effectively suppresses non‐radiative decay and minimizes dark current, while energy‐level‐offset‐governed electron transfer between acceptors maintains efficient charge transport. This synergistic mechanism collectively enables remarkable device performance, including high detectivity and ...
