Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

In previous work we looked in detail at simulations of our HTS Resistive DC SQUIDs (RSQUIDs) using a lumped-component model and neglecting step-edge junction capacitance. These can now be made with junctions that have a high product of critical current and normal resistance (IcRJ) and so the Josephson frequency can be above 1 THz. This calls for a more refined model of the device, which we will present here. The RSQUID series resistor is represented as a distributed combination of resistance and inductance, rather than simply a resistor in series with its self inductance. We now include junction capacitance, as the Stewart-McCumber parameter can be close to unity. We treat the RSQUID loop as a co-planar stripline, rather than as an inductor. We report a range of simulations with these enhancements to the model and comment briefly on the results in relation to potential applications of RSQUIDs as active microwave devices.
