Abstract
An efficient and consistent methodology is developed in this paper for the precise evaluation of unknown dielectric permittivity media parameters involved in the design of 3-D waveguide structures. In essence, the selected configuration is numerically solved for a set of predetermined permittivity values by means of a time-domain (herein, the finite-difference time-domain) technique at least twice, depending on the desired level of accuracy. Finally, implementing the Monge-Kantorovich mass transfer problem formulation, the required fields are rigorously evaluated for a broader range of values, as substantiated by the results obtained from various realistic arrangements.
