✦ Synopsis

Three different infrared filter designs are described for application in high-efficiency thermo¨oltaic power systems. They are two-dimensional periodic grid arrays with square-loop, circular-loop, or ( ) cross aperture or slot elements printed on thin dielectric films. These three filters' bandpass performances are demonstrated to transmit the wa¨elength that can be efficiently con¨erted to electricity, and to reflect other wa¨elengths back to the heat source, hence conser¨ing energy and increasing the power system's efficiency. The design with cross slot ( elements exhibits the highest Q bandpass property or the fastest cutoff ) for out-of-band wa¨elength .
