A superconducting electromagnetic filter arrangement uses two filters, one of which is fabricated from thin film high temperature superconductor (HTS) material and one of which is fabricated from thick film HTS material. Using both thick and thin film technologies exploits the advantages of each technology. The thick film HTS filter may be fabricated from conventional thick film materials or may be fabricated from all temperature performance (ATP) materials that allow the thick film filter to work at super-critical temperatures.
