Spherical wave to plane wave

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.
