Transient field of circular plane aperture

Abstract

Radiation of the wave front of an ultrashort pulse from a plane circular aperture was calculated. Analyzes of pulse propagation character was provided. The features of the wave front, the formation of a side impulse in particular, are considered. The technique of obtaining the pulse response characteristic from the known input and output signals of the system is shown. Numerical results are compared with the theoretical antiderivatives of the PRC.
