Abstract :
A variational principle based on duality is developed which is related to the complementary variational principle recently established. As a result, classes of solutions other than those normally obtained can be found for the characteristic impedance of TEM lines. In principle, two separate upper and two separate lower bounds can be determined. A simple example, for which the exact solution is known, is used to illustrate the methods.
