Electromagnetics activities at Lawrence Livermore National Laboratory

Over the past several years, electromagnetics as an electrical engineering activity has increased to a fairly substantial level at Lawrence Livermore National Laboratory. While EM has long been of interest in various Laboratory's physics programs (magnetic and inertial-confinement fusion, nuclear weapon's effects, radar blackout, and the like), its importance in engineering is a more recent development. This engineering interest in EM originated largely from concern over EMP effects on electronic systems but has since expanded to a broader range of applications. In this report we will highlight three areas of current emphasis: geophysical applications, transient measurements, and field-particle modeling. Also discussed is a low-level on-going activity in dissemination of computer codes for EM modeling.
