MetadataShow full item record
This thesis examines the coupling effects of electromagnetic fields to the interior of aviation platforms during electromagnetic vulnerability (EMV) testing and the potential of resonant frequency field enhancements. Interior fields of a cylindrical slotted cylinder (approximate half scale model representation of the Black Hawk helicopter) were measured with and without the presence of a ground plane. Maximum permissible exposure (MPE) limits are presented as well as MPE measurements interior to different helicopter platforms. Lastly, the effects these measured fields have on testing are examined.
