Abstract

When Government drawings, specifications, or other data are used for any purpose other than in c'onnection with a definitely related Goveznment pzocurement operation, the United States Government thereby izncurs no responsibility nor any obligation whatsoever; and the fact that the gove.-zment may have forimilated. furnished, or in any way supplied the said drawings, specifications, or other data, is not to be regarded by implication or otherwise as "*n any manner licensing the holder or any other person or corporation, or conveying any rights or permission to manufacture, use, or sell any patented invention that may in any way be related thereto. This report .has been reviewed by the :nformation Office (O) and is releasable to the National Techznical Information Service (NTIS). Pt NTIS, ir will be available to the general public, including foreign nations. This technical report has been reviewed and is approved for publication.

Electromagnetic Interaction of Lightning with Aircraft

“…The only known application of the EFIE method to the lightning-coupling problem has been the code WIRANT [37] which has been applied to a …”

“…Let S be the surface of the body, S1 the surface of the aperture, and V and V1 be the volume of the body and the enclosed cavity, respectively. The field everywhere in space is broken up into three components: E=Ei Fs + EP (37) H H ±H±s + n v1 cV t= t1 + ts + tp (37) and A s Ai + As + AP (38) where E, H is the total field, FP, Hi is the incident field produced by a distant transmitter, s, fS is the field scattered by the body with no aperture and no cavity present, and F", HP is the "perturbed field"-the difference between the scattered field with and without the aperture and cavity present. …”

“…distributed over S, produce the correct total field inside S (E and 14) and the perturbed field (EP and H4P) outside S. Substituting (37) and (38) …”
