Finite-difference time-domain predictions of HIRF penetration into a Boeing 757

The penetration of high intensity radiated fields (HIRF) into the fuselage of a Boeing 757-200 is calculated using the finite-difference time-domain method. The FDTD predictions will eventually be compared with in-flight measurements as part of the validation phase of a study into all-electronic commercial aircraft technology. Ultimately, avionic systems and components would be tested in the lab under the illumination levels predicted to exist at the systems installed locations in the aircraft. This is in contrast to expensive and hazardous full-aircraft testing.
