Cylindrical harmonics

• abstract: In mathematics, the cylindrical harmonics are a set of linearly independent solutions to Laplace's differential equation, \nabla^2 V = 0, expressed in cylindrical coordinates, ρ (radial coordinate), φ (polar angle), and z (height). Each function Vn(k) is the product of three terms, each depending on one coordinate alone.
