At present EMC clearance of an aircraft is performed by experimental testing alone: there is no alternative source of information concerning the finished platform's susceptibility characteristics. This cannot be said to be an entirely satisfactory state of affairs for several reasons. Also, the severity of EMC problems is likely to get worse with the increasing use of imperfectly conducting materials for aircraft construction. It would therefore be of considerable practical benefit if some form of trustworthy, independent supplementary procedure existed for determining susceptibility characteristics. This overall aim of the work described here is to assess the usefulness of computational techniques in this regard: in particular, the prediction of currents induced upon cables located on aircraft-like structures. The configuration studied is based on the low-level swept current (LLSC) test used in aircraft clearance.
