On transmission line resonances in high TC dc SQUIDs

Abstract

In this paper, we study transmission line resonances in high TC dc SQUIDs (superconducting quantum interference devices). These resonances are exhibited in the characteristics of SQUIDs which are fabricated on substrates with high dielectric constant, such as strontium titanate. The power balance equation is analytically derived both for symmetric and for asymmetric SQUIDs. Using this, we investigate SQUID current-voltage I(V), voltage-flux V (Φ) and voltage modulation ΔV characteristics.
