An SbD-QCTO Approach to the Synthesis of Isotropic Metamaterial Lenses

Within the transformation electromagnetics (TE) framework, an innovative approach, based on the System-by-Design paradigm, is proposed for the synthesis of isotropic nonmagnetic metamaterial lenses. Selected numerical results, concerned with an application of the SbD-QCTO approach, are reported to give some insights on its advantages and current limitations in terms of computational efficiency, effectiveness, and flexibility.
