Surface Current and Charge Density Induced on Aircraft

The usefulness of the geometrical theory of diffraction (GTD) in computing the surface current and charge density induced on aircraft is illustrated. This is a high-frequency solution for an arbitrary incident plane wave and fuselage observation points. A pattem is presented for an arbitrary incident plane wave as well as a series of frequency and time domain plots for roil plane incidence. A 3-dimensional pattem is presented for plane wave incidence (as a function of incidence angle) as well as examples of roll plane results in both the frequency and time domain.
