Abstract

In A, electrical shock wave devices L1 and L2 of equal length are arranged in parallel and connected across constant voltage source 1. The latter is of sufficient magnitude to support but not initiate shock waves in L1 and L2. Portions of each device L1 and L2 adjacent the respective output ends are cross coupled, e.g., capacitively, along conductors 3 and 5, respectively, to portions of the other device adjacent the input end. To initiate oscillations, input pulse 7 applied at input terminals 9 is capacitively coupled to initiate a shock wave in L1 which propagate s in the direction of the arrow. The shock wave propagated along L1 is sensed and applied along conductor 3 to initiate a shock wave in L2 which propagates in the direction of the arrow.

High Frequency Devices Based on Electrical Shock Waves

In A, electrical shock wave devices L1 and L2 of equal length are arranged in parallel and connected across constant voltage source 1. The latter is of sufficient magnitude to support but not initiate shock waves in L1 and L2. Portions of each device L1 and L2 adjacent the respective output ends are cross coupled, e.g., capacitively, along conductors 3 and 5, respectively, to portions of the other device adjacent the input end. To initiate oscillations, input pulse 7 applied at input terminals 9 is capacitively coupled to initiate a shock wave in L1 which propagate s in the direction of the arrow. The shock wave propagated along L1 is sensed and applied along conductor 3 to initiate a shock wave in L2 which propagates in the direction of the arrow. Under certain operational circumstances, it is desirable to incorporate amplification when capacitively coupling a signal between electrical shock wave devices. The shock wave propagated along L2 is, in turn, sensed and applied along conductor 5 to reinitiate a shock wave L1. When a shock wave appears at the output end of either L1 or L2, the resistivity is momentarily reduced so that a current pulse appears between output terminals 11 and 13. The operation of L1 and L2 is self- sustaining and a series of current pulses is provided between terminals 11 and
13.

In B, electrical shock wave devices L1...L3 of equal length are connected in series across constant current source 15. The latter is of sufficient magnitude to sustain but not initiate shock waves. To trigger the arrangement, input pulse 17 is applied at input terminals 19 to initiate a shock wave along L1 in the direction of the arrow. The shock wave propagating along L1 is sensed and applied along conductor 21 to initiate a shock wave in L2. While the shock wave is propagating along L2, the appearance of a shock wave at the output end of L1 momentarily reduces its resistance. Thus, a voltage pulse appears between terminals 23 and
25. Similarly, the shock wave propagated along L2 is sensed and applied along conductor 27 to initiate a shock wave in L3. This, in turn, is sensed and applied along conductor 29 to the input end of L1. Thus, the operation of the series arrangement...
