    Several dielectric-waveguide components utilizing appropriate metallized surface structures on dielectric ceramics are examined. Using magnetic walls, easily realized with ceramics, several dielectric components of a type quite different from conventional hollow waveguide components have been fabricated. Multistage bandpass filters (BPFs) with tandem connection of quarter-wave resonators have been... View full abstract»

    RADARSAT, the first Canadian remote-sensing spacecraft, is designed to provide Earth observation information for five years. The satellite is scheduled for launch in 1994. The only payload instrument is a 5.6-cm-wavelength (C-band) synthetic aperture imaging radar (SAR). RADARSAT will gather data on command for up to 28 min during each cycle of its 800-km (nominal) near-polar orbit. Image... View full abstract»
