ABSTRACT:
Waveform configuration and/or power accumulation are accomplished with a ial transmission line that includes a pair of electrodes. One electrode is segmented to have at least two independent sections disposed in radial sequence relative to an axis passing perpendicularly through the electrodes. Individual voltage levels are applied between each independent section and the other electrode, while optical switches are disposed between each radially adjacent pair of independent sections for controlling electrical conductivity therebetween. The magnitude of the individual voltages, as well as the phasing of the optical switches are determined in accordance with the desired waveform configuration and power level. For purposes of power accumulation only, a plurality of such radial transmission lines may be connected in series to a load through a coaxial waveguide, with each being arranged to generate the same waveform, while the waveform generated by each is delayed to enhance the cumulative waveform amplitude that passes thereto from the immediately preceding radial transmisison line in the conductive path to the load.
