dte.f and dbess.f (required by dte.f)
by Keith Lysiak

"... calculates the exact solution for the near fields in and around a 2-D cylinder. This is for the 2-D TE case. ... The code is for "near" fields and due to the limits on the number of HANKLE functions, it will not work if a large area relative to the size of the cylinder is chosen. The code could be modified to perform far field approximations to eliminate this problem. ... I also have coding for the TM case but it has not been thoroughly checked out. I provide it on an individual case with that understanding. I can be contacted at: klysiak@swri.edu".
