Outline of Final Research Achievements

Frequency selective surfaces (FSS) of Jerusalem cross slot array (JCSA) type and Maltese cross slot array (MCSA) type were designed for separating the submillimeter-wave band around 600 GHz by the method-of-moment calculations in view of future application to spaceborne submillimeter-wave spectrometric radiometer. Based on the designs, the FSSs were fabricated by applying a photolithographic process. By measuring the fabricated FSSs, we confirmed that both types of FSSs were fabricated with sufficient accuracies to achieve the desired reflection and transmission characteristics. It was also confirmed by numerical calculations that a transmission bandwidth as wide as 120 GHz could be achieved by double-layering the MCSA type FSS.
