Title
(EN) SUPERCONDUCTING ELECTROMAGNETIC WAVE SENSOR
(FR) CAPTEUR D'ONDES ÉLECTROMAGNÉTIQUES SUPRACONDUCTEUR
Abstract
(EN) An electromagnetic wave sensor (1) of extremely high sensitivity comprises a spin filter junction formed by an insulating layer (30) arranged between a metal electrode (20) and a superconducting layer (10) carrying an exchange field for providing a spin splitting effect of charge carriers (63, 64), an antenna comprising a wave collecting element (60) in contact with said superconducting layer to convey external electromagnetic waves (61) generated by an external source, and an electric measurement device (70) in contact with said metal electrode to measure an electric current or voltage caused by said spin split charge carrier flow, arranged to provide an output signal (71) responsive to the amplitude and frequency of said external electromagnetic waves.
(FR) Capteur d'ondes électromagnétiques (1) de sensibilité extrêmement élevée, comprenant une jonction à filtration de spin formée par une couche isolante (30) intercalée entre une électrode métallique (20) et une couche supraconductrice (10) portant un champ d'échange permettant de fournir un effet de division de spin de porteurs de charge (63, 64), une antenne comportant un élément collecteur d'onde (60) disposé en contact avec ladite couche supraconductrice afin d'assurer le transport des ondes électromagnétiques externes (61) générées par une source externe, et un dispositif de mesure électrique (70) disposé en contact avec ladite électrode métallique afin d'assurer la mesure d'un courant ou d'une tension électrique dû-e au flux porteur de charge spin, afin de fournir un signal de sortie (71) en réaction à l'amplitude et la fréquence de ces ondes électromagnétiques externes.
