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. WebThe rst part is simply the leading term of the expansion corresp onding to the degree and order zero term The Asso ciated Legendre F unction P has a v alue of one as do es the C co e cien ... aluation of the spherical harmonic expansion requires ev aluating the Asso ciated Legendre F unctions This ev aluation is most con v enien

University of Toronto. A multipole expansion is a mathematical series representing a function that depends on angles—usually the two angles on a sphere. These series are useful because they can often be truncated, meaning that only the first few terms need to be retained for a good approximation to the original function. blackbeard ranch florida
