Abstract:
The feasibility of air breakdown initiation by a quasi-optical subcritical-field microwave beam has been studied experimentally. Breakdown has been initiated by a linear electromagnetic vibrator, which was placed in a traveling electromagnetic wave (i) on the surface of a dielectric sheet that faces wavevector $\mathbf{k}$ of the wave, (ii) on the opposite surface of the sheet, and (iii) near the sheet. Fields induced at the ends of the vibrator have been calculated theoretically for all arrangements. Numerical estimates and experimental data have shown that when a vibrator is placed on a dielectric surface, electrical breakdown of air may be initiated in a much deeper subcritical field of the microwave beam than when it is placed in the field of a traveling microwave.
