Abstract
A method of solving the diffraction problem for a linear monochromatic emitter with arbitrary electromagnetic pulse (EMP) and arbitrary spaciotemporal dependence of the source is developed for a linear monochromatic emitter. The theory reveals a small-scale modulation of the spectrum and a change of the EMP form during the time of passage of the current pulse through the emitter when the time of passage of the current pulse through the emitter is of the order of the pulse duration and at characteristic wavelengths compatible with the emitter dimensions. The refraction, reflection and absorption of EMP generated in the atmosphere are estimated.
