Resumo

An ultrashort electromagnetic pulse energy and duration propagating along the radiation axis in the far zone are determined in two ways: by the shape of its electric field strength and by the energy spectrum. In both cases, the pulse energy is the same and the duration as well as peak amplitude differ by tens of percent. A comparative assessment is given for the energy dissipated in semiconductor elements of automated technical means irradiated by ultrashort and rectangular microwave frequency pulses. It is shown that the impact of a microwave pulse is better effective at carrier frequencies of the order of hundreds of megahertz and less.
