“…The design of modern high-performance microwave devices such as filters [1], directional couplers [2], and antennas [3], generally involves a number of challenging and (sometimes) contrasting requirements on their electromagnetic (EM) behavior along with tight geometrical, weight, and cost constraints [4]. Such a synthesis problem is often formulated as a singleobjective optimization problem (SOP) whose solution is the global minimum of a cost function that quantifies the mismatch between the EM/structural features of the synthesized device and the user-defined objectives.…”

The computationally-efficient solution of multi-objective optimization problems (MOPs) arising in the design of modern electromagnetic (EM) microwave devices is addressed. Towards this end, a novel System-by-Design (SbD) method is developed to effectively explore the solution space and to provide the decision maker with a set of optimal trade-off solutions minimizing multiple and (generally) contrasting objectives. The proposed MO-SbD method proves a high computational efficiency, with a remarkable time saving with respect to a competitive state-of-the-art MOP solution strategy, thanks to the "smart" integration of evolutionary-inspired concepts and operators with artificial intelligence (AI) and machine learning (ML) techniques. Representative numerical results are reported to provide the interested users with useful insights and guidelines on the proposed optimization method as well as to assess its effectiveness in designing mm-wave automotive radar antennas.

Herein, stacked layers of copper selenide thin films comprising Au nanosheets in its structure are fabricated and characterized. The CuSe/Au/CuSe (CAC) thin films are prepared by the thermal evaporation technique under a vacuum pressure of 10−5 mbar. It is shown that Au nanosheets improve the stoichiometric growth of the CuSe thin films and induce the structural phase transitions from cubic to hexagonal. In addition, the in situ monitoring of the structural modifications in the CAC in the temperature range of 293–473 K proves the permanent enhanced crystallinity of the films. Optically, while the Au nanosheets increase the light absorbability and redshifts the energy band gap of CuSe, the in situ heating blueshifts the energy band gap. Moreover, insertion of Au nanosheets between layers of CuSe and heating them at 473 K significantly increase the dielectric constant and the optical conductivity by more than five times. Moreover, the drift mobility of charged carriers, the scattering time at femtosecond level, and the plasmon frequency are remarkably enhanced. Values of plasmon frequency exceed 6.0 GHz nominating the CAC films as signal receivers suitable for 5G technology.

Silicon‐based packaging is highly suitable for miniaturised and cost‐effective integrated systems. However, traditional silicon‐based antenna‐in‐package (AiP) has disadvantages, such as high loss, low efficiency and narrow bandwidth. A glass‐silicon active package system architecture is proposed. Its active part is integrated on a silicon substrate, while the antenna array in the package system is made of glass, which has high radiation efficiency. The proposed antenna structure is an H‐type aperture‐coupled microstrip patch antenna. The authors use a ball grid array to form cavity and two shielding structures to improve the scanning performance of the array. Furthermore, by adding grounding points, the resonance singularity within the shielding structure is eliminated. A test array, composed of 8 × 8 elements was fabricated for the purpose of validating the design. It can achieve wide‐angle scanning greater than ±60° and bandwidth of 29%. This design can be applied for ka‐band communications and radar systems.
