A Uniqueness Theorem for Initial-Boundary Value Problems in Tellegen Medium

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.
