Some critical avionic systems require cooling air via vents on the side of the aircraft, thus creating leakage points for high‐intensity electromagnetic radiation. This paper presents a novel application of high‐intensity radiated field (HIRF) shielding using a rectangular waveguide array, while maintaining cooling airflow requirements. Signal attenuation versus frequency and depth of the array has been calculated using closed‐form equations. The simulation and measurement results are in good agreement with the calculated values. © 2004 Wiley Periodicals, Inc.
