Surface currents on triangular and square metal cylinders

Measurements were made of the surface current density, on highly conducting triangular and square cylinders when the cylinders were illuminated by a plane wave whose direction of polarization was either parallel or perpendicular to the axis of the cylinder. The angle of incidence of the illuminating wave, size of the cylinder, and direction of polarization of the wave were taken as parameters. The errors associated with the current loop probe, when located near the edges, were quantitatively studied. Comparisons with the available computer-calculated results[1]-[3] were made whenever possible.
