The aim of this note is to demonstrate that the electromagnetic field, in the time domain, sustained by a point charge moving at a constant velocity along the axis of a circular waveguide can be expanded by means of a Fourier-Bessel series. This expansion is rapidly convergent in the complementary range of the classical integral representations, namely for large values of \z' - vt'\. Quickly convergent expansions are necessary for tracking codes to simulate beam dynamics in accelerators.

Abstract
The aim of this note is to demonstrate that the electromagnetic field, in the time domain, sustained by a point charge moving at a constant velocity along the axis of a circular waveguide can be expanded by means of a Fourier-Bessel series. This expansion is rapidly convergent in the complementary range of the classical integral representations, namely for large values of \z' - vt'\. Quickly convergent expansions are necessary for tracking codes to simulate beam dynamics in accelerators.File in questo prodotto:
