Article Abstract

Beyond 5G networks would require newer technologies to deliver a smarter network. In accordance with these requirements, an electronically steerable compact antenna system capable of beam-switching in the azimuth plane is proposed. The design uses a monopole antenna as the main radiator surrounded by metasurface-based electronically reconfigurable reflector elements designed for the sub-6GHz range. The reflector elements use a reconfigurable capacitively loaded loop (CLL) which can be electronically activated to work as an artificial magnetic conductor (AMC). The design offers a digitally controllable directional radiation pattern covering all 360° in the azimuth plane with a step-size of 30°, a directional gain of dBi and a high front-to-back lobe ratio (FBR) of dB. The compact and modular nature of the design combined with the use of commercial off-the-shelf (COTS) components and 3D-printing makes the design low-cost and easier to integrate with various internet of thing (IoT) applications.

An axiomatic system engineering design method based on NSGA-II algorithm applied to complex systems.

This study proposes an integrated framework that combines Axiomatic Design with Model-Based Systems Engineering, incorporating NSGA-II as an intelligent optimization engine. The framework constructs a multi-level traceability matrix linking requirements, functions, behaviors, and structural elements, and leverages NSGA-II to dynamically optimize the sequencing of the Design Structure Matrix, thereby enhancing the explicitness and visualization of coupling relationships. Rather than directly eliminating dependencies, the approach aims to support a more systematic modularity-oriented analysis.

Metalenses are ultrathin optical components enabling precise wavefront control via the use of engineered nanostructures and are traditionally fabricated as standalone elements. Herein, we demonstrated their integration with other optical components, particularly a distributed Bragg reflector mirror structure. Using nanoimprint lithography (NIL), we fabricated a metalens with a numerical aperture of 0.

Biogenic guanine crystals widely distributed in organisms form ordered multi-level micro- and nano- structures and function as optical materials including reflectors, imaging mirrors, and photonic crystals for manipulating light. It is difficult to design green camouflage materials based on chlorophylls due to its poor photo and thermal stability under natural environment. Herein, a functional green camouflage biomimetic material based on chlorophyll derivative chlorophylls-Cu occluded into the crystal lattices of single crystalline anhydrous guanine microplates was designed, which exhibit high reflectivity and strong depolarization feature in the visible and near infrared range.

The ability to fabricate materials and devices at small scales by design has resulted in tremendous technological progress. However, the need for engineered three-dimensional (3D) nanoscale materials requires new strategies for organizing nanocomponents. Here we demonstrate an inverse design approach for the assembly of nanoparticles into hierarchically ordered 3D organizations using DNA voxels with directional, addressable bonds.
