We propose to identify, prototype and test a conformal boundary algorithm for use in finite-difference electromagnetic particle-in-cell codes. The algorithm that is selected will be 2nd order accurate and have a minimum reduction in the Courant time step. The prototype will implemented in the plasma simulation framework VORPAL, building on existing conformal boundaries in the VORPAL code. We will run tests of the algorithm for a variety of cavity shapes in both 2D and 3D.
