Abstract

1,030,225. Waveguide dissipative loads. FERRANTI Ltd. April 22, 1963 [April 25, 1962], No. 15703/62. Heading H1W. A dissipative waveguide load comprises a short-circuited length of waveguide made of a resistive ferromagnetic material having a Curie temperature low enough to be reached during normal operation of the load. A suitable material, is 42% nickel iron having a Curie point of 360‹ C. The load may take the form of two flat coils of rectangular waveguide mounted side-byside with their inner ends joined and their outer ends providing respectively a short-circuit and an input coupling means. Radiating fins may be provided. Wave energy entering the load is dissipated at first mostly in the region of the input coupling, but as the temperature rises and the Curie point is reached, the attenuation in this part of the load decreases. Thus the region providing attenuation gradually advances along the guide.
