In physics, the plane-wave expansion expre … In physics, the plane-wave expansion expresses a plane wave as a linear combination of spherical waves: where
* i is the imaginary unit,
* k is a wave vector of length k,
* r is a position vector of length r,
* jℓ are spherical Bessel functions,
* Pℓ are Legendre polynomials, and
* the hat ^ denotes the unit vector. In the special case where k is aligned with the z axis, where θ is the spherical polar angle of r.where θ is the spherical polar angle of r.
