Parallel plate waveguide
A technique for the accurate computation of the electromagnetic ﬁelds radiated by a charged particle moving within a parallel-plate waveguide is presented. Based on a transformation of the time-varying current density of the particle into a time-harmonic current density, this technique allows the evaluation of the radiated electromagnetic ﬁelds both in the frequency and time domains, as well as in the near- and far-ﬁeld regions. For this purpose, several accelerated versions of the parallel-plate Green’s function in the frequency domain have been considered. The theory has been successfully applied to the multipactor discharge occurring within a two metal-plates region. The proposed formulation has been tested with a particle-in-cell code based on the ﬁnite- difference time-domain method, obtaining good agreement.
