Abstract
The mechanism of self-oscillation onset in a short-circuited long line segment in a mode of undistorted oscillation transmission, active loss exclusion and simultaneously affecting electric and wave resonances has been analytically and experimentally confirmed. Such a mode has been achieved owing to a certain relationship between the specific parameters of a symmetrical cable. The exclusion of active loss becomes possible when the input resistance of a short-circuited long line segment amounts to the wave resistance characterizing a line length corresponding to one-eighth of the wavelength under free oscillations acting at a frequency exhibited by a quarter-wave line due to connecting a capacitive element parallel to the input ends of the line. Electrical resonance has been achieved in an oscillatory circuit formed by the equivalent inductivity of a short-circuited long line segment and a capacity connected to the input ends of the line. The wave resonance in the absence of active losses is accompanied by a multifold increase in current at the end of the line with each wave pass along the line, while the voltage across the input of the line changes its sign with each wave pass. Owing to the presence of a capacitive element, both voltage across the input of the line, and current at the end of the line exhibit a multifold increase, which leads to an even greater increase in current. This process is avalanche-like. The field of practical application of the revealed self-oscillation mode can be rather extensive.
