Abstract :
In this paper we provide numerical simulations for modeling an array of non-locally coupled DC SQUIDs that are coupled through the magnetic field created by the circulating current. The motivation is based on work using an array of non-identical SQUID loops or SQIFs to produce a non-periodic voltage response with a unique anti-peak centered at the zero applied flux. Our approach differs by using an array of identical SQUID loops and varying the spacing between each of these loops. Certain distributions of spacing between SQUIDs demonstrate the anti-peak response as seen in the SQIF.
