Summary form only given. Simulations of high power microwave (HPM) devices are dominated by FDTD PIC methods developed by Yee and Boris. This work focuses on extending these techniques to a nested hierarchy of grids for the purpose of adding local refinement. A second order conservative algorithm is presented for the electromagnetics. Furthermore, a novel current weighting scheme is presented for the coarse/fine interface which reduces spurious radiation and provides a smooth divergence-free transition across the interface
