... wavelength limit we have seen that a reasonably good description of the diffracted fields is obtained by approxi- mating the tangential electric field in the aperture by its unperturbed incident value . For longer wavelengths this ...

... Wavelength Limit Another type of problem which is essentially diffraction is the scattering of waves by an obstacle . We will consider the scattering of a plane electromagnetic wave by a perfectly conducting obstacle whose dimensions ...
