The Coupling of High Intensity Radio Frequency (HIRF) Environments into Aircraft

In this paper the interaction of the High Intensity Radio Frequency (HIRF) environment with aircraft is described. This environment is assuming more importance because of the use of composite materials and low level semiconductor technology which performs critical functions. Experimental coupling results are presented and discussed for induced cable currents at low frequencies, and for internal fields at high frequencies. A major portion of the paper is used to describe numerical techniques which can be used to solve the coupling problem.
