Thus, … WebJan 7, 2014 · One of the steps to prove Kirchhoff's diffraction equation is to use Green's second identity. This identity shows the relation between the solutions in the volume and boundary. The two solutions - are two scalar functions phi and psi that generate a vector field trough: A = phi*del (psi). all till now is just definitions.
Green's second identity establishes a relationship between second and (the divergence of) first order derivatives of two scalar functions. In differential form In vector diffraction theory, two versions of Green's second identity are introduced. One variant invokes the divergence of a cross product and states … See more In mathematics, Green's identities are a set of three identities in vector calculus relating the bulk with the boundary of a region on which differential operators act. They are named after the mathematician George Green, … See more Green's third identity derives from the second identity by choosing φ = G, where the Green's function G is taken to be a fundamental solution of the Laplace operator, ∆.
