WebWhen the wavelength of a wave field is larger than the ‘‘aperture’’ sizes of the diffraction device used to control the wave, the scalar diffraction theory can be used. Even when this is not true, scalar diffraction theory has been found to be quite accurate [Mellin and Nordin, 2001]. Scalar diffraction theory involves the WebWe shall restrict attention to the simplest (and, fortunately, the most widely useful) case: a monochromatic scalar wave Ψ = ψ(x)e−iωt(8.1a) with ﬁeld variable ψthat satisﬁes the Helmholtz equation ∇2ψ+k2ψ= 0 , with k= ω/c , (8.1b) except at boundaries. how does making an insurance claim work
