Metamaterial-by-Design-A Paradigm for the Industrial Synthesis of em Manipulation Devices

An overview of the metamaterial-by-design (MBD) paradigm as applied to the industrial synthesis of electromagnetic (EM) manipulation devices is provided. Thanks to the MbD, the constituent materials of innovative EM devices are regarded as additional degrees-of-freedom (DoF s) allowing to match several conflicting user-defined performance and/or geometric constraints. Innovative applications of the MbD to the multi-scale design of wide angle impedance matching (WAIM) layers and metamaterial lenses are presented, together with an illustrative example concerned with the conformal transformation of linear phased arrays through a novel Schwarz-Christoffel transformation optics (SCTO) MbD technique.
