A variational solution for the scattering of electromagnetic pulses from a cylinder of finite length by W. J Welch( Book )

2 editions published in 1961 in English and held by 2 WorldCat member libraries worldwide

The problem of the scattering of an essentially plane electromagnetic pulse by a thin metallic cylinder of finite length is treated by means of a variational formula derived in an earlier paper (IRE PGAP Vol. AP-8, No. 1:68, Jan. 1960). The pulse is a delta function, and it is assumed that the current induced on the scatterer is a damped sinusoid with the frequency of oscillation such that the cylinder is one half wavelength long and the damping due to radiation. The characteristic damping is calculated by a related variational technique. The time dependence of the echo at a large distance from the cylinder is plotted for two different thicknesses of the cylinder. (Author)
