Abstract

The design of microwave devices requires the interaction of electromagnetic fields to be simulated with charged particle flow with high accuracy. The methods involved have to be, in particular, well adapted to the geometrical complexity of real devices, especially to take into account the 3-D effects. We have investigated a numerical method for solving the 3-D time dependent Vlasov-Maxwell equations in the relativistic case, on unstructured meshes. We present some numerical results obtained by simulating a three-dimensional virtual cathode system, and compare the resulting high power microwave radiation with a theoretical estimation.
