Abstract:

This paper presents the optimum design method for Low Radar Cross Section (LRCS) composite plates by means of electromagnetic reflection coefficient of multilayer dielectrics and optimization techniques. A computer code based on this method has been developed for optimum design for LRCS composite plates. Two examples are given in order to verify this code. The code is a useful tool for aircraft designers in selecting structural materials and designing structure of LRCS aircraft.
