A method of numerical solution of the complete system of Maxwell equations is used to investigate the process of interaction of a short electromagnetic pulse with a long conductive cylinder (a two-dimensional scattering problem). Reflected signal waveforms and spectra are calculated for various relationships between the pulse length and the sizes of the scatterer. It is demonstrated that for incident pulse length smaller than the diameter of the cylinder, two pulses of scattered radiation are formed in the far field zone.
