A laser phased array directed energy system has been designed and simulated. Lubin and Hughes calculated the requirements and possibilities for DE-STAR systems of several sizes, ranging from a desktop ...

Researchers have recently demonstrated the most complex 2-D optical phased array ever. A new 2-D optical phased array technology will enable advanced LADAR and other defense applications. Most people ...

This is an update of the system under development by John Brophy and his team and it will use a kilometer-scale, multi-hundred-megawatt phased-array laser to beam power to a vehicle that converts it ...

Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G ...

This past Friday was not a good day for asteroid-human relations with asteroid 2012 DA14 passing a mere 27,700 km (17,200 miles) from the Earth just a few hours after a meteor exploded over the ...

Potentially hazardous asteroids are still looming large in the minds of scientists engaged in planetary defense issues. Numerous strategies describing deflection of near-Earth objects (NEOs) have been ...

In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...
