Purdue University researchers have shown that a single photon can control light by using a silicon single-photon avalanche diode as an optical modulator, allowing one visible photon to influence a ...
Abstract: Most conventional reconfigurable transmitarrays rely on multilayer frequency-selective surfaces and PIN diodes, limiting transmittance and multibit modulation, which constrains beamforming ...
Abstract: This paper designs a phase-shifting millimeter-wave device with adjustable phase, based on the theory of composite right/left-handed transmission lines and varactor diodes. The phase-shifter ...
