The analysis of electromagnetic scattering from a jet engine with complex termination is a very difficult task because the electrical size of the engine cavity is very large and the geometry of the engine termination is very complex. In this paper, the shooting‐and‐bouncing rays (SBR) method is employed to analyze electromagnetic scattering from jet engines with complex termination. In order to accelerate the ray tracing and to economize the computation memory, the multiplaten z ‐buffer algorithm is employed to model the jet engine. Two jet engine models with complex termination are analyzed. Excellent results are obtained for the two models. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 281–284, 1999.
