Beno Zerr Â· ENSTA Bretagne. Bessel functions are used to solve in 3D the wave equation at a given (harmonic) frequency. The solution is generally a sum of spherical bessels functions that gives the acoustic pressure at a given location of the 3D space.
Bessel functions are a series of solutions to a second order di erential equation that arise in. many diverse situations. This paper derives the Bessel functions through use of a series solution. to a di erential equation, develops the di erent kinds of Bessel functions, and explores the topic. of zeroes. Finally, Bessel functions are found to be the solution to the Schroedinger equation in a. situation with cylindrical symmetry.
