Electromagnetic Airframe Penetration Measurements of a Beechcraft Premier IA



Chriss A. Grosvenor, David R. Novotny, Dennis G. Camell, Galen H. Koepke, Robert Johnk


The National Institute of Standards and Technology has recently completed shielding effectiveness/penetration studies on three different aircraft types for the Federal Aviation Administration.  The studies are used to understand the cavity coupling characteristics between antennas placed in various compartments inside the aircraft and antennas placed at various angular positions around an aircraft. This document will show how penetration varies as a function of frequency, antenna type, antenna polarization, and cavity susceptibility.  Internal coupling between two antennas placed in the aircraft at different locations to determine the quality factor and the time decay of fields is also presented.  These measurements will provide the Federal Aviation Administration with a database on penetration for three different classes of aircraft.
