Abstract

We propose to build upon the conformal boundary models that currently exist in the VORPAL plasma simulation framework for both the electromagnetic and particle-in-cell (PIC) models in code. These improvements will include 2nd order accurate conformal boundary models for the electromagnetics with no reduction in the Courant time step, models for low noise removal of particles at conformal boundaries, and field emission of particles at conformal boundaries. New PIC models with a higher order current weighting will also be studied. These improvements will be tested in simulations of high-powered microwave devices such as magnetrons.
