I know only that they are useful in waveguides and related toipcs.

Re: bessel function

now i know that bessel function is used in communication (FM transmision analysis.)

Re: bessel function

hi
this function is very useful in the electromagnetic.
for example in Waveguides , solved poisson laplace and etc.
for more information reffer to Electromagnetic's book.

Re: bessel function

Bessel function is the solution of a special second order differential equation. It is used in many applications.

Please see the David Cheng's book (Field and Wave Electromagnetics) page. 563.

Re: bessel function

Functions bessel and neyman play the same role for the systems with the azimuthal symmetry, such as sin and cos play for the systems with the translation symmetry.

Re: bessel function

hi
for example
i solve this equation in cylindrical coordinates.
