Abstract
Frequency-selective surfaces provide efficient beamsplitting of energy in the millimetre and submillimetre wavebands and therefore are being employed as quasioptical components for front end channel demultiplexing and single sideband filtering in radiometers. The paper some of the current progress in developing this technology, and in particular shows how novel design approaches have been employed to tailor the transmission response of the filters and overcome some of the fabrication problems. Experimental and simulated results in the frequency range 500GHz validate the design technique and highlight the insertion loss mechanismsKeywords
