The efficient design of compact antennas operating over multiple bands suitable for the Internet of Things (IoT) is addressed by means of an instance of the system-by-design (SbD) paradigm. More specifically, an iterative strategy that combines different software modules for the search spaceexploration, the fast physicalmodeling of the radiators, and the quality evaluation of the guess solutions is...
The design of multi-band patch antennas is addressed within the System-by-Design (SbD) paradigm. A fast optimization-driven strategy combining customized tools for the effective exploration of the solution space and the efficient evaluation of the antenna radiation performance is proposed. Toward this aim, an Ordinary Kriging (OK) predictor is used as a surrogate model of the cost function while the...
The instantiation/customization of the recently introduced System-by-Design (SbD) paradigm to the solution of multiscale and multiphysics synthesis problems is discussed in this work. Towards this end, the SbD fundamental concepts are illustrated (starting from the composition of elementary functional blocks up to the derivation of an integrated SbD design loop) together with the basic structure and...
The latest advances on the System-by-Design (SbD) paradigm, proposed for enabling the optimization-based design of complex electromagnetic systems and devices, are presented in this work. The integration of a suitable synthesis block and an analysis block based on surrogate modeling is described as a multi-step process aimed at identifying the minimum number of parameters/degrees-of-freedom of the...
An innovative approach based on the System-by-Design (SbD) paradigm is presented for radome design. The method is based on the integration of a Synthesis Block with an efficient Analysis Block based on a surrogate model for the emulation of the cost function. Some preliminary numerical results are reported in order to show the effectiveness of the proposed design methodology.
The design of complex antenna devices is addressed in this work through an instance of the System-by-Design (SbD) paradigm. Towards this end, an approach combining different functional blocks that enable the exploration of the search space, the antenna modeling from the physical viewpoint, and the evaluation of the quality of each trial design is introduced. An innovative algorithm that combines the...
The synthesis of high-performance and complex electromagnetic devices is carried out through an innovative approach. The features of metasurfaces and metamaterials are exploited to design innovative field manipulation devices. More in detail, a set of instances of the System-by-Design paradigm are applied to the synthesis of metasurface and metamaterial-enhanced electromagnetic devices in order to...
This paper is aimed at analyzing and discussing the key-role of the evolutionary optimization in EM device synthesis carried out within the recently developed System-by-Design paradigm. Towards this end, SbD models the design process as an eco-system of functional blocks (for the synthesis/analysis of each sub-part of the overall complex system) suitably connected to enable different trade-off solutions...
A new paradigm for handling complexity in large system design is introduced. The so-called System-by-Design paradigm is based on the representation of the design procedure in terms of a set of interconnected functional blocks, each one associated to a different design functionality (synthesis, analysis, configuration, optimization, etc.) referring to a sub-part of the overall system. The advantages...
