What I am asking for is essentially a 2D Fourier transform of the cylindrical harmonics.

In cylindrical coordinates, the most appropriate solutions are the two kinds of Hankel functions, representing outgoing and incoming wave solutions. Home Questions Tags Users Unanswered. Please google before posting. Your views and inputs are greatly appreciated.

Knowing the laws of refraction, I can calculate the currents and arrange by Fourier components so that there is a net resultant of just a single line of current on the boundary. Your hxnkel will never hannkel result because there is “k” in the integrand that is not numeric.

The expansion you’re looking for is derived in this articlewhich I found immediately as one of the first hits of a Google search for “hankel plane waves”. Email Required, but never shown. Let us assume a 2D space, and at fixed temporal frequency, the equation reduces to the Helmholtz equation.

The waves that make this field distribution in the vaccuum are the evanescent waves which result from total internal reflection of the ordinary waves sub the dielectric glue. For electromagnetic waves, there are currents flowing in the boundary of two mediums. I would like to know how to perform numeric integration for the following type of integrals in Mathematica. That’s the beauty of it!

However, a Hankel function’s real part is a bessel function while its imaginary part is a 2nd kind Bessel function Neumann function with a singularity at the origin. Numerical integration of Hankel functions Ask Question. I was sort of hoping someone had already done the hard work for me: Mathematics Stack Exchange works hanksl with JavaScript enabled.

You will notice that is an angular spectrum decomposition of a uniaxial diffraction problem Fourier transform in 1D only. Victor Liu 3, 11 Sign up using Facebook. Can you try along the same direction as your other question ? Kamov Sergey 9.

It is well know that planewaves are a complete basis for solutions to the wave equation. I found this article, but it addresses us completely different problem, actually.

If cylindrical hanmel are a complete basis, is there a closed form expression relating them to planewaves?
