Design of a tunable multichannel terahertz absorber in one-dimensional photonic crystals incorporating a Dirac semimetal-dielectric defect layer B. Rezaei Article 20 February 2025|Open Access Predicting three-dimensional chaotic systems with four qubit quantum systems ...
An interface device is provided for coupling a host device having a network interface to a computer network having a predetermined communications medium and a predetermined communications physical layer. The interface device comprises a plug member having a first connector affixed to it for coupling to...
1b, c. Operating in the physical layer allows the isolation of unwanted transmissions in the analogue domain, reducing the risk of privacy leakage by eliminating the need to record the transmission content digitally19. Such a “blindness” feature is also critically demanded by recovering the ...
