The E-2 airborne command and control aircraft, a platform that has been in service for more than 60-years, will receive upgrades under the forthcoming E-2D Advanced Hawkeye Block II iteration for use ...

This paper developed a photonically actuated ultrawideband, two-dimensional transmit array using a Fourier optical lens as a beamformer. Data encoding was developed, in which custom IF signal/data can ...

Precise modulation of the focused beam is a critical technology for improving the performance of ultrasound-based treatments and diagnostics. Beyond conventional 1D transducer arrays, 2D transducer ...
