Re: "Projector of the Sharpest Beam of Electric Waves"
WebBeamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience destructive interference. Beamforming can be used … WebSep 9, 2011 · One of Uda’s first projects was to design a vacuum-tube oscillator that would operate at wavelengths of’around 440 cm.
