The integral equation for the current induced on a thin, perfectly conducting strip of infinite length above a homogeneous conducting half-space is examined for an incident field with E parallel to the strip axis. A closed form quasi-static solution is obtained for the case when the width and elevation of the strip are small compared to the skin depth (or wavelength for a lossless medium) in the lower region. Results are presented which compare the quasi-static solution with a numerical solution of the exact integral equation.
