HIGH TEMPERATURE SUPERCONDUCTOR TUNABLE FILTER

摘要

A circuit is provided wherein the electrical properties of the circuit are varied by a magnetic actuator. The circuit includes a fixed substrate (10) a nd a movable substrate (15). The magnetic actuator comprises magnetic drivers (30) on an upper surface of fixed substrate (10) that is substantially overlapped by HTS reaction plates (35) on the lower surface of movable substrate (15). A tuning current applied through a continuous strip of HTS material (51) in the magnetic driver induces a repulsive magnetic force in t he HTS reaction plate, thereby causing the movable substrate (15) to move with respect to the fixed substrate (10).
