Superconducting Quantum Interference Devices Arranged in Pyramid Shaped Arrays

We explore SQUID array designs that could be beneficial in a robust 3-D structure involving several substrates and find a design for which there may be some advantages in linearity and dynamic range. Traditional substrates are square in shape, for a 3-D structure three squares would need to be attached together to create a structure with three sides of a cube. We explored how we would arrange an array of SQUIDs on this structure if the substrates were cut into triangles. This would result in a three-sided pyramid (or tetrahedron) shape. The arrays have a feed line at the top entering a single SQUID (or small array) and the number of SQUIDs (small arrays) increased in number each row and a decreasing critical current. We simulated the effects of varying the critical currents and SQUID loop sizes on the average response output and determined that for arrays of 21 10 × 10 bi-SQUIDs have a more linear anti-peak and larger voltage swing than a comparable size 35 × 60 array.
