“…While standard quadrature techniques can accurately evaluate the spatial changes in current, the polar technique also accurately captures the temporal variations in current, helping to lower the necessary timestep for stability. This integration technique is presented in section two of [12], attached. Section three of [12] also presents an exploration of a multilevel fast method for the BEM hybrid kernel.…”

“…This research effort extended previous work to include hexahedral finite elements for the solution of the coupled first-order Maxwell's equations. In addition, it incorporated numerous stability enhancements to the boundary condition, such as sub-cycling the boundary element segment of the problem [11] and using highly exact polar integration [12].…”

This is the final report for LDRD 01-ERD-005. The Principle Investigator was Robert Sharpe. Collaborators included Niel Madsen, Benjamin Fasenfest, John D. Rockway, of the Defense Sciences Engineering Division (DSED), Vikram Jandhyala and James Pingenot from the University of Washington, and Mark Stowell of the Center for Applications Development and Software Engineering (CADSE). It should be noted that Benjamin Fasenfest and Mark Stowell were partially supported under other funding.The purpose of this LDRD effort was to enhance LLNL's computational electromagnetics capability in the area of broadband radiation and scattering. For radiation and scattering problems our transient EM codes are limited by the approximate Radiation Boundary Conditions (RBC's) used to model the radiation into an infinite space. Improved RBC's were researched, developed, and incorporated into the existing EMSolve finite-element code to provide a 10-100x improvement in the accuracy of the boundary conditions. Section I provides an introduction to the project and the project goals. Section II provides a summary of the project's research and accomplishments as presented in the attached papers.
