Considering for a moment just the 0th order bessel function, you can map from this circular distribution into a 1-dimensional Fourier transform giving just the radial component of the wave. I once worked out a method to get the Neumann functions in terms of plane waves by physical reasoning.

Considering for a moment just the 0th order bessel function, you can map from this circular distribution into a 1-dimensional Fourier transform giving just the radial component of hajkel wave. 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.

The waves that make this field distribution in the vaccuum are the evanescent waves which result from total internal reflection of the ordinary waves inside the dielectric glue.

Then hankwl you take the analytical continuation, that is, the same function greater than 1, you get the Fourier transform of the Neumann function; that is, the radial component of it. Mathematica Stack Exchange works best with JavaScript enabled.

I was sort of hoping someone had already done the udb work for me: I arrange for sine waves to arrive on the boundary from the left so they create currents on the boundary.

For electromagnetic waves, there are currents flowing in the boundary of two mediums. This limiting argument is interesting, but could you back it up with a bit more analysis? This is tricky, hankeel here’s how I did it. Sign up using Facebook.

It is well know that planewaves are a complete basis for solutions to the wave equation. I think you know that if you take haniel uniform distribution of sine waves in all different directions in 2d space, in phase at the origin, you get the Bessel functions; the 0th order if they are in phase about the circle, the 1st order if they phase ranges over degrees around the circle, etc.

In cylindrical coordinates, the most appropriate solutions are the two kinds of Hankel functions, representing outgoing and incoming wave solutions. I would like to know how to perform numeric integration for the following type of integrals in Mathematica.

Email Required, but never shown. Kamov Sergey 9.

The resulting field in the vaccuum must be physically correct, and it is made up of the evanescent portion of the incident waves from the left hand side. Please point out when you cross-post; not doing so unnecessarily duplicates efforts.

I found this article, but it addresses a completely different problem, actually. Your views and inputs are greatly appreciated.
