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 GEMACS 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.
