SQUID Arrays in the Corbino Geometry

We introduce here a novel SQUID array design based upon the well-known Corbino geometry into which selected simple and/or complex physical (inductive and/or current flow) symmetries and asymmetries can be imposed. Via simulation, we analyze the resulting behavior of three simple 1D parallel Corbino SQA designs having perpendicular axes of symmetry and asymmetry with respect to the inductive properties of the individual SQUID elements. Through the Corbino geometry, it becomes possible to construct circuits having closed boundary conditions for the parallel rows and concentric rings connected in series. The work presented herein is intended to set the basis for investigating the potential use of this novel geometry in developing “right” and “left” hand sensitive 2D SQAs, improving linearity over standard 2D designs, as well as implementing designs having responses dependent upon asymmetry of the imposing field.
