Abstract :
A frequency dependent inductance estimation has been carried out for Rapid-Single-Flux Quantum (RSFQ) applications in NbN multilayer technology up to frequencies above the NbN gap frequency. For this purpose an extension of the fullwave modified transverse resonance method (MTRM) has been used, in which each superconducting layer is characterized by its complex conductivity according to the BCS derived model of Mattis and Bardeen. Our estimation shows significant influence of the gap frequency on the NbN multilayer structure inductance at high frequencies.
