WebSpherical Wave Expansion of Vector Plane Wave In discussing the scattering or absorption of electromagnetic radiation by localized systems, it is useful to be able to express a plane electromagnetic wave as a superposition of spherical waves. Consider, first of all, the expansion of a scalar plane wave as a set of scalar spherical waves. WebApr 14, 2024 · In this section, the spherical wave solution is employed in determining the diffracted field at a position P in the half-space behind an aperture. The goal is to determine a scalar field \tilde {\psi } which fulfils the Helmholtz Eq. 3.5. Figure 3.1 a displays the geometry of the problem.
