High-Tc Superconductor sub-mm wave heterodyne receiver for environmental monitoring


Foreseen Results

The active elements will be integrated into the receiver, and the receiver performance will be characterised. With the help of external expertise, design and parameters of the receiver will be optimised for environmental monitoring.
A heterodyne receiver suitable for environmental monitoring will be developed, based on high-Tc superconductor Josephson junctions (JJ). The Josephson mixing scheme will be used and as mixer element a single JJ or a small array of JJ incorporated into the antenna design will be fabricated. Also, arrays of high-Tc JJ will be developed, with the aim of their application as local oscillator (LO). The fabrication of an integrated receiver consisting of a JJ mixer and a JJ LO is expected. Different technologies for high-Tc thin film and JJ fabrication will be tested - laser ablation, magnetron sputtering, and co-evaporation. Different substrates with relatively small dielectric losses will be investigated. The optimal technology will be selected after microwave characterisation of the samples. The possibility of using intrinsic stacked JJ as LO will be investigated.
