A New Channel-Base Current Model for Lightning-Induced Voltage Calculations
No full textWe propose a new channel-base current model, which is particularly well suited for lightning-induced voltage calculations. We will show that this new proposal meets a significant number of characteristics required to these applications, and favorably compares to existing solutions
Bunched beams in axisymmetric systems
No full textWe analyse, in this paper, the self field of a bunched beam in a cylindrical metallic pipe with arbitrary density. The field is calculated by superposition of the Green's functions of the single charge in the pipe. A general solution is given as a Bessel-Fourier expansion, which is characterised by very good convergence properties. This allows the evaluation of the dynamics of a large class of physical beams by using this kind of solution for the self field. As an example the field is calculated for the case of a parabolic radial and elliptic longitudinal density profile
