(Phys.org)—An arbitrary waveform generator can, as its name implies, generate waves of almost any shape by controlling the amplitude, frequency, phase, and other wave characteristics. Waveform generators working in the ...
(PhysOrg.com) -- The rule that nothing can travel faster than the speed of light, c, is one of the most fundamental laws of nature. But since this speed limit has only been experimentally demonstrated for information carried ...
(Phys.org)—Imagine a cell phone charger that recharges your phone remotely without even knowing where it is; a device that targets and destroys tumors, wherever they are in the body; or a security field that can disable ...
