I always get amused by comments such as this.  FEA is merely the establishment of
a set of trial functions which are valid over a specific region in the domain
(rather than the total domain), and which are typically constructed in such a
way that the valid domain need not be rectilinear.  As such, virtually every
numerical method is a subset of FEA (I admit to some issues with Boundary
Element Methods).  I am unsure of the details of your transmission line method,
but the implications are that it is a specific class of FEA.  I would be
interested in more comments (and I will dredge up the journal article!).
