Special Issue Information

Dear Colleagues,

Metamaterials are macroscopic composite materials with periodic subwavelength structures whose electromagnetic properties can be controlled not only by varying the chemical composition but also by engineering the shape of the meta-atoms and their internal structures, as well as the mutual positions and orientations of the meta-atoms in the composite material. In general, the symmetry and asymmetry of the structure is a crucial factor in the design of metamaterials, as well as the engineering of the optimal properties for specific applications.

In recent years, metamaterials have established themselves as one of the most important topics in physics and engineering and have found practical applications across a wide variety of fields, including photonics, condensed matter physics, materials science, and biological and medical physics.

In the foreseeable future, we may see applications that drive the optimal design of engineered materials and surfaces, reconfigurable, adaptive and software-defined metamaterials, etc.

This Special Issue of Symmetry features articles on recent advances in metamaterial and asymmetry/symmetry, showcasing both fundamental research and applications, as well as shared advances in theory, numerical modeling, and experiments. We welcome both original research and review articles.

Topics of interest include, but are not limited to, bound states in the continuum in metamaterials, strong coupling in metamaterials, topological properties in metamaterials, nonlinear and quantum effects in metamaterials, novel optical phenomena in metamaterials, and optical and optoelectronic devices based on metamaterials.

Submit your paper and select the Journal “Symmetry” and the Special Issue “Advances in Metamaterial and Symmetry/Asymmetry” via: MDPI submission system. Our papers will be published on a rolling basis, and we will be pleased to receive your submission once you have finished it.

This article describes the development of a compact microstrip bandpass filter (BPF) for multiple wireless communication utilizations. The proposed bandpass filter consists of metamaterial unit cells that are symmetrical in shape. The design process involves the placement of four symmetrical split-ring resonators (SRRs) on the top plane of the BPF. It exhibits improved filter characteristics through the implementation of these SRRs. The filter was modeled and fabricated and its performance was evaluated using a Vector Network Analyzer. The designed bandpass filter shows a 5 GHz bandwidth covering the frequency band spanning from 1 to 5.2 GHz, with a quality factor value of 1.85 across 1.9 GHz, 3.3 across 3.3 GHz and 5.1 across 5.1 GHz. The metamaterial analysis was carried out using ANSYS ELECTRONIC DESKTOP. The proposed filter measures 20 × 18 × 1.6 mm3, which is significantly smaller than current filters. The designed bandpass filter occupies 50% of the space of a conventional filter. The designed bandpass filter exhibits a distributed surface current of 84 A/m, and 94 A/m across the wide- and narrow-band operating frequency. The simulated and measured results indicate that the suggested metamaterial filter is well-suited for multiband wireless applications like GPS (1.57 GHz), WLAN (2.4, 3.6, and 5.2 GHz), Wi-MAX (2.3, 2.5, and 3.5 GHz), and ISM (2.5 GHz).
