Abstract

An attempt has been made to improve the FDTD (finite-difference time-domain) formalism for electromagnetic coupling through composite material by taking into account the imperfect contact between the loading material and the rim of the aperture. The low frequency domain is still assumed. The results of the FDTD code ALICE are first compared with analytical results. A code validation is then obtained with experimental data. Experimental transient electromagnetic fields were obtained on the French military Transall C 160 aircraft during in-flight lightning strikes. The measurements allowed a more precise determination of the internal magnetic field behind a composite panel located on the forward fuselage.<>
