Magnetostatic Oscillators for Generation of Ultra-Short Waves

An electronic oscillator of the magnetostatic type, for generating wavelengths of less than 50 centimeters, is described. The operating characteristics of this oscillator are given, with particular reference to obtaining maximum output and efficiency. A thorough experimental investigation of the effect of inclining the magnetic field is presented, and its importance in obtaining maximum output is discussed. Experimental curves showing the effect of various factors on frequency are given. Measurements of power output and efficiency are described, and the results compared to a Barkhausen-Kurz oscillator.
