High Tc Superconductors and Signal processing

This research line concern the study of high temperature superconducting materials (HTSC) and related materials, and their application in the microwave domain.

Three principal axes are developed :
- Digital signal processing and realisation of logical circuits based on Josephson Jonctions HTSC
- Analogic processing of microwave signals based on HTSC. This axis include frequency generation, fixed and tuneable filters, and design of HTSC based receivers.
- Vortex dynamics on HTSC, from dc to microwave
