Abstract

Summary form only given. Asymptotic methods have been widely used to evaluate inter-antenna electromagnetic compatibility (EMC) between aircraft-mounted antennas in cases where the aircraft exterior surfaces can be considered to exhibit perfect conductivity. In other cases, the asymptotic methods have proven less attractive owing, to a significant degree, to the unavailability of a Green´s function suitable for representing creeping-ray fields on or near surfaces which are not perfect conductors. Such a Green´s function is supplied here for the case of a simple impedance boundary condition.
