In a similar way, a cylindrical wave has a cross-section that is an expanding circular wave that has an infinite extent along its axial direction. From: …
In mathematics, the Jacobi–Anger expansion (or Jacobi–Anger identity) is an expansion of exponentials of trigonometric functions in the basis of their harmonics. It is useful in physics (for example, to convert between plane waves and cylindrical waves), and in signal processing (to describe FM signals). This identity is named after the 19th-century mathematicians Carl Jacobi and Carl Theodor Anger. WebThe propagation of a wave packet in space is a superposition of particle waves of a number of frequencies. We look at one frequency component, assuming that we can construct a wave packet as needed. The scattering problem assumes that the wave packet (particle) moves freely at a distance far from a scattering center, both before and after ...
WebCylindrical waves, i.e. the product of a Hankel function of integer order times a sinusoidal angular factor, often occur in diffraction theory.
