Quasioptical modeling of wave beams with and without mode conversion. II. Numerical simulations of singlemode beams
Abstract
This work continues a series of papers where we propose an algorithm for the quasioptical modeling of electromagnetic beams with and without mode conversion. The general theory was reported in the first paper of this series, where a parabolic partial differential equation was derived for the field envelope that may contain one or multiple modes with close group velocities. Here, we present a corresponding code paraxial ray description and its test applications to singlemode beams in vacuum and also in inhomogeneous magnetized plasma. Here, the numerical results are compared with analytic formulas from Gaussianbeam optics and also with coldplasma ray tracing, respectively. The quasioptical simulations of modeconverting beams are reported in the third paper of this series.
