%0 Journal Article %T A Uniqueness Theorem for Initial-Boundary Value Problems in Tellegen Medium %A Burhanettin S. Altan %J PIER C %D 2008 %I EMW Publishing %R 10.2528/PIERC08011504 %X Uniqueness of the initial-boundary value problems for a Tellegen media is studied. Initial-boundary value problems for a Tellegen Medium are summarized for the sake completeness; the conservation of energy for such a medium is reviewed. Sufficient conditions are given for the positive definiteness of the energy stored in a Tellegen media due to the fields. It is shown that the if the energy stored in a Tellegen medium is positive definite, then an initialboundary value problem for a Tellegen media has only one solution, if it exists. %U http://www.jpier.org/pierc/pier.php?paper=08011504
