Abstract

1,106,429. Waveguide dissipative loads. MARCONI CO. Ltd. 20 Oct., 1966 [4 Nov., 1965], No. 46799/65. Heading H1W. An R.F. load device includes a length of tapered waveguide having means providing a water space within the guide which extends along and is adjacent to at least one wall of the guide. A membrane 5 of plastics material forms a water-flow passage 6 with one of the narrower walls 1 of a tapered rectangular waveguide, the narrow end of which is small enough to ensure a cut-off frequency such that energy propagation from that end of the tube is prevented. Alternatively, the water passage may extend around every wall of the waveguide. In another embodiment (Figs. 3 and 4, not shown) a glass tube through which water is circulated is seated in a groove formed in an interior wall of the tapered waveguide such that part of its circumference projects into the waveguide, any space between the tube and the groove being filled with a material of high dielectric constant to prevent damage due to corona discharge.
