Validation of GEMACS (General Electromagnetic Model for the Analysis of Complex Systems) for Modeling Lightning-Induced Electromagnetic Fields.

Abstract

The General Electromagnetic Model for the Analysis of Complex Systems (GEMACS) is used to model and perform a frequency domain analysis on specially instrumented Air Force Lightning Test Object (LTO). The predicted results are compared to experimental data to evaluate GEMAC'S ability to predict electromagnetic (EM) fields around the LTO. A previous elementary GEMACS study modeled an airplane and compared the results to lightning data collected inflight. Limitations of that effort included geometric modeling where some parts of the airplane were modeled more accurately than others and limited analysis bandwidth. The small bandwidth used in that GEMACs analysis made comparisons with the inflight data difficult because the inflight data had a much larger bandwidth.
