  • Abstract
    It has been proved that the current phase relation of a \´short\´ weak link in the \´dirty\´ limit at absolute zero Kelvin is expressed in a Fourier series as I = {\\pi\\Delta \\over 2eR} {{\\infty \\atop \\sum} \\atop n=1} {(-1)^{n+1} \\over n^{2} - {1 \\over 4}} \\hbox{ sin } n\\psi . We have realized \´short\´ weak links with a three-dimensionnal geometrical structure. Fabrication techniques of the \´short\´ weak links have been disclosed. We have made 115 GHz Josephson-effect mixers of the \´short\´ weak links.
