English to French Tech/Engineering Engineering (general) detector of microwave radiation

contexte

"said absorber element , said variable impedance element , and said heating element are coupled to each other through superconductor sections of lengths shorter than any of said first, second, and third lengths of superconductor to allow hot electron diffusion between said absorber element, said variable impedance element, and said heating element while blocking quasiparticle thermal transport of heat through said first, second, and third lengths of superconductor."

"It is an objective of the present invention to present a detector and detector arrangement for detecting microwave radiation with extremely high sensitivity and relative ease of calibration. Another objective of the invention is to present a method and devices for calibrating a detector of microwave radiation without causing significant increase in the heat capacity of the detector element. These and further advantageous objectives of the invention are achieved by providing a heating element in the detector that is closely enough coupled to the other parts of the detector so that the hot electron effect can be exploited, while simultaneously using long enough superconducting leads to block stray heat conduction carried by quasiparticle thermal transport."

"The Wiedemann-Franz law has been found to not hold for superconductors: a material that is electrically superconductive relatively good insulator, thermal conduction through electron diffusion and quasiparticle thermal transport"
