Diffraction When light passes an edge, it will deviate from rectilinear propagation. This phenomenon (which is a natural consequence of the wave nature of light) is known as diffraction and plays an important role in optics. The term diffraction has been conveniently deﬁned by Sommerfeld as ‘any deviation from rectilinear paths which cannot be interpreted as reﬂection or refraction’. A rigorous theory of diffraction is quite complicated. Here we develop expressions for the diffracted ﬁeld based on Huygens’ principle of secondary spherical wavelets. It is a very fortunate coincidence that the aperture and the diffracted far ﬁeld are connected by a...
