Abstract

A circuit is provided wherein the electronic properties of the circuit are varied by a magnetic actuator. The circuit includes a fixed substrate and a movable substrate. The magnetic actuator comprises a magnetic driver on an upper surface of the fixed substrate that is substantially overlapped by an HTS reaction plate on the lower surface of the fixed substrate. A tuning current applied through a continuous strip of HTS material in the magnetic driver induces a repulsive magnetic force causing the movable substrate to move with respect to the fixed substrate.
