Limiting Power of High Power Microwave Pulses from Aperture

Abstract:

Based on the field equivalence principle and the potential function, the axial normalized pulsed power density of the microwave radiated from the circle aperture antenna was deduced. The power density in the Fresnel region was calculated for uniform aperture and tapered one. The relations between the aperture antenna’s maximum power and the parameters including pulse width, aperture radius and the center frequency were analyzed. The formula of the antenna’s maximum power limited by the air breakdown due to high power microwave is presented.
