NEC-LIST: Current on an Infinitely Long Cylindrical Wire

Back in 1979 and 1980, Jack Richmond published papers in which he discussed
the calculation of the admittance of an infinitely long wire excited by a
magnetic frill. In those papers he mentions "an efficient subroutine",
YFIN, that performs the necessary calculations.

I have programmed up my version of the formula, but it is numerically very
expensive. I need to improve matters. I have communicated with some
people at OSU, but YFIN apparently no longer exists there. I am therefore
asking members of the group if they have a copy of YFIN that they can
provide - or any alternatives.

Many thanks.
