Development and Application of Compatible Discretizations of Maxwell's Equations

Wednesday, May 12, 2004 - 3:00pm - 4:00pm

This talk will be an overview of a variety of electromagnetics problems that are of interest to LLNL, and of the numerical methods that have been developed to solve these problems. We will briefly discuss the history of Finite Difference Time Domain methods Discrete Surface Integral methods, and Discrete Differential Form based Finite Element Methods. Our current research efforts are in the area of higher-order finite elements, higher-order time integration, and hybrid finite element boundary element simulations, and we will present recent results in these areas. Applications that we are applying these algorithms to include: photonic bandgap structures, linear accelerators, wave propagation in random environments, and microwave circuits.

This represents joint work with Joe Koning and Rob Rieben
