B. Jacobs and J. S. Hesthaven, J. Comput. Phys. 214, 96 (2006)] method. We show that typical damping rates measured in particle-in-cell (PIC) simulations can differ significantly from the linearized Landau damping coefficient and propose a simple numerical method to solve the plasma dispersion function exactly for moderate to high damping rates. Simulation results show a high degree of agreement between the high-order PIC results and this calculated theoretical damping rate.</style></abstract><notes><style face="normal" font="default" size="100%">(c) 2011: American Institute of Physics</style></notes><reprint-edition><style face="normal" font="default" size="100%">2011-11</style></reprint-edition></record></records></xml>
