Radiation-enhanced dual-inverted bowlers antenna for high-power mesoband system.

We propose a novel radiation-enhanced dual-inverted bowlers antenna to pursue a maximal radiated electric field (E-field). Based on increasing the stored energy and the high-frequency component of the excitation pulse, the new structure significantly improves the radiation performance without increasing the generator output voltage or antenna size. Computer simulations show that the radiated E-field increases by a factor of 2.

Note: Design and investigation of a multichannel plasma-jet triggered gas switch.

We described the fabrication and testing of a multichannel plasma-jet triggered gas switch (MPJTGS). A novel six-channel annular micro-plasma-gun was embedded in the trigger electrode to generate multichannel plasma jets as a nanosecond trigger pulse arrived. The gas breakdown in multiple sites of the spark gap was induced and fixed around jet orifices by the plasma jets.

A novel low-jitter plasma-jet triggered gas switch operated at a low working coefficient.

In this paper, we described the fabrication and testing of a novel plasma-jet triggered gas switch (PJTGS) operated at extremely low working coefficients with excellent triggered jitters. While the structure of the PJTGS is similar to that of a traditional three-electrode field-distortion gas switch, to improve its triggered performance we used a conical micro-plasma-gun with a needle-to-plate spark gap embedded in the trigger electrode. Applying a nanosecond pulse to the trigger electrode caused a spark discharge in the micro-plasma-gun.
