    In general, this paper deals with the generation and practical utilization of ultra-short waves below ten meters. The first part of the paper describes an ultra-high-frequency oscillator in which a "tank circuit" of novel design is used for the purpose of obtaining a high degree of frequency stabilization without resorting to frequency doubling or crystal control. Later, the feasibility of utilizi... View full abstract»

    The requirements for satisfactory operation of a lapel microphone are shown to be (1) a wide band frequency characteristic compensated for diffraction of the voice around the head, (2) means for keeping the output constant while the head is turned, (3) satisfactory sensitivity, and (4) light weight. The first is accomplished by calculating the diffraction and compensating for it. The second is acc... View full abstract»

    A system of tuning is described by which the current distribution and therefore the radiating properties of an antenna, may be varied over an extremely wide range. This is effected by means of a localized capacity and inductance connected to the top of the radiator. The capacity may conveniently take the form of a sphere, a cylinder, or a disk. The inductance may take the form of a coil housed wit... View full abstract»

  • An Electron Oscillator with Plane Electrodes

    This paper describes a new type of thermionic tube capable of producing ultra-high frequencies by means of electron oscillations. Tubes of this type are characterized by having parallel plane electrodes, instead of cylindrical electrodes as in the conventional Barkhausen-Kurz tubes, and a fourth element called a backing plate. The relations between wavelength and amplitude of oscillation and the v... View full abstract»

    The function of the electron gun irrespective of the purpose for which the cathode ray tube is used is to generate, to concentrate, to control, and to focus an electron beam to a spot of a desired size. This paper describes the theory of the above-mentioned functions. The point of view of electron optics is presented and the theory of thick electron lenses with variable indexes of refraction is gi... View full abstract»
