Abstract: 1,176,965. Masers. CUTLER-HAMMER Inc. 22 Aug., 1967 [22 Aug., 1966], No. 38710/67. Heading H1C. A travelling-wave apparatus, for example a maser, has a biasing magnetic field acting transversely to the direction of propogation of a signal through the device, the field strength varying as a function of position in the direction of the field. Waveguide 10 has conductive rods 15 extending from one wall to form a travelling wave comb structure. A paramagnetic maser active material 25, e.g. ruby, is arranged above the comb structure and a low-loss, non-paramagnetic dielectric material 27 is arranged below the comb to equalize the dielectric loading. Ferromagnetic discs or spheres are arranged along the dielectric to attenuate waves travelling in the backward direction. Material 27 may be replaced by a paramagnetic material identical to material 25. Soft magnetic rods 32, 33 are placed on each side of waveguide 10, disposed asymmetrically with respect to member 25. The rods distort the magnetic biasing field H 0  so that the field intensity varies across the width of the member 25. Since the signal frequency which is amplified by the active medium depends on the field strength, the distortion of the field increases the bandwidth of the device. Preferably, the field intensity gradient also varies across the active medium in such a manner that the gain for all signal frequencies within the amplified bandwidth is the same. The calculations necessary to determine the positions of the rods 32, 33 and the dimensions of the active medium for a selected frequency band are described.
