P22.5. A plane wave, of wavelength λ, is normally incident from a vacuum on a large, perfectly conducting sheet. A circular loop of radius a (a < λ) should be at a location at which the induced emf is maximal, as near as possible to the sheet. If the electric field of the incident wave is E, calculate this maximal...
