    In order to obtain amplification over a wide band of frequencies, a tube having high transconductance and low input and output capacitance is required. A grid-controlled inductive-output tube having these attributes and giving 10 watts output at 500 megacycles is described. A high ratio of transconductance to input capacitance is attained by close cathode-grid spacing and large grid-screen spacing, the latter made possible by use of a very high screen voltage. A low output capacitance is obtained by the use of an inductive-output arrangement which requires no power dissipation by the output electrodes. The design of the output circuit for low inherent capacitance is facilitated by the use of magnetic lenses to focus the electron beam. These lenses can be energized by a permanent magnet. Loading caused by secondary electron emission from the current collector is eliminated. The performance of the tube as a wide-band amplifier is described. View full abstract»

    Composite radiating or receiving systems for ultra-high frequencies may be built with electromagnetic horns as elements that are so positioned and interconnected as to produce the desired characteristics. Several different arrangements are discussed theoretically and experiments made at a wavelength of 8.3 centimeters are described. View full abstract»

    It is shown that the usual nonperiodic solution of d2y -+ e(1 + k cos t)y = 0 dt2can always be interpreted in the stable case as a wave undergoing simultaneous phase and amplitude modutlation. An analysis is carried through on this basis. View full abstract»

    Data on the ordinary-wave critical frequencies and virtual heights of the ionospheric layers are presented for the period indicated in the title. The monthly average values of the maximum usable frequencies for undisturbed days, for radio transmission by way of the regular layers is also provided. View full abstract»
