Summary:
A current continuity equation is proposed as the additional equation for the GTDMM hybrid technique formulation to acquire the uniqueness of the solution which were nonexistent in the conventional formulation with the matchingpoint equation. The current continuity equation, which ensures the current continuity and satisfies the boundary condition, can directly be written down through equating the MMregion current to the GTDregion current at the regions boundary. It is proved that the current continuity equation is equivalent to the matchingpoint equation of special case when the matchingpoint located very close to the boundary, which were able to give the best solution in the conventional formulation with the matchingpoint equation as explained by Burnside et al. The validity of the new equation is confirmed through the numerical results.
