Traveling wave electric discharge oscillator with directional coupling connections to a traveling wave structure wherein the number of coupling connections times the phase shift between adjacent connections equal an integral number of wavelengths

Claim 1

AN ELECTRIC DISCHARGE OSCILLATOR DEVICE COMPRISING A CATHODE, A PERIODIC SLOW WAVE HIGH Q ANODE STRUCTURE SURROUNDING SAID CATHODE, SAID CATHODE AND ANODE STRUCTURE DEFINING A REENTRANT SLOW WAVE MODE OF OSCILLATION AT PARPORTING A DESIRED TRAVELING WAVE MODE OF OSCILLATION AT PARTICULAR OPERATING FREQUENCIES, ONLY A SINGLE TRANSMISSION LINE CONCENTRIC WITH SAID ANODE STRUCTURE AND INCLUDING AN OUTPUT COUPLING PORT AT ONE END AND REVERSE TERMINATING MEANS AT THE OPPOSITE END THEREOF, DIRECTIONAL COUPLING MEANS COMPRISING A PLURALITY OF COUPLING CONNECTIONS SYMMETRICALLY EQUALLY SPACED COMPLETELY ABOUT SAID ANODE STRUCTURE AND CONNECTING EACH PERIOD SECTION THEREOF WITH SAID TRANSMISSION LINE FOR DIRECTIONALLY COUPLING ENERGY TOWARD ONLY SAID OUTPUT COUPLING PORT IN SAID TRANSMISSION LINE, THE NUMBER OF COUPLING CONNECTIONS TIMES THE PHASE SHIFT BETWEEN ADJACENT COUPLING CONNECTIONS BEIN EQUAL TO AN INTEGRAL NUMBER OF WAVELENGTHS, AND MEANS IN SAID TRANSMISSION LINE ELECTRICALLY SEPARATING SAID OUTPUT PORT AND REVERSE TERMINATING MEANS INTERMEDIATE AND ADJACENT PAIR OF COUPLING CONNECTIONS.
