Note: z-components 2-dim vector potential 2-dim Laplace Eqn. conductor constant on conductor surface 2-dim Laplace Eqn. has no local extrema (see Griffith 3.1.3)! Now: if cross-section is star shaped: => within conductor same for => only trivial solution TEM modes exist only in coaxial cobles Lecture Notes Page 2
