Yes, I reached your equations (albeit clumsily) when I extended my treatment of the copper pipe a little, to deal with the solid rod. I see why you doubt if it's Bessel's equation. It's the imaginary multiplied constant on the right which is the problem? I'm afraid DEs whose solutions are special functions aren't my line of country. Good luck!
