System-by-design paradigm as applied to the synthesis of innovative field manipulation devices including task-oriented metamaterials

The System-by-Design (SbD) paradigm is adopted in this work in order to synthesize innovative microwave devices comprising task-oriented engineered materials. More in detail, the synthesis problem is formulated in the SbD framework in terms of the combination of a set of elementary functional blocks, each one devoted to the analysis/synthesis of a specific portion of the target device (e.g., the electromagnetic characterization of the material, the simulation of the device comprising the engineered material, the configuration of the material unit cell). The design blocks are then combined in an overall SbD loop to yield an integrated design procedure which is able to fully exploit the degrees of freedom available in the design to satisfy the physical/performance applicative constraints with the minimum costs, andmaximum efficiency and scalability. Representative numerical examples will be reported in the presentation concerning the design of different wave manipulating devices within the proposed SbD approach.
