Special Issue Information

Dear Colleagues,

The design of electromagnetic devices has long been limited by natural materials. As demands grow for miniaturization, multi-functionality, and tunability in optics and communications, conventional materials are increasingly inadequate. This has driven the development of metasurfaces and metamaterials—artificially engineered structures that manipulate waves at subwavelength scales. With exceptional design flexibility and unique electromagnetic properties, they open new possibilities for controlling wave–matter interactions.

The scope of this Special Issue, entitled "Innovations in Metasurfaces and Metamaterials Design", encompasses, but is not limited to, novel design methodologies, advanced materials, advanced fabrication techniques, theoretical modeling, and diverse applications of metasurfaces and metamaterials. This includes topics such as reconfigurable and intelligent metasurfaces; all-dielectric metamaterials; topological metamaterials; and their applications in areas like novel antennas, microwave devices, sensing, energy harvesting, and RF and optical stealth. We cordially invite researchers to contribute original research articles or comprehensive reviews that explore the latest advancements and future prospects in metasurface and metamaterial technologies.

There is a substantial demand for lightweight, low-profile, and conformal antenna integration on the wing platforms of unmanned aerial vehicles (UAVs). This paper presents an S-band (2–4 GHz) flexible conformal metasurface array antenna based on a highly conductive graphene-assembled film (GAF). The main contributions of this work are twofold. First, flexible and highly conductive GAF is used as the conductor together with a flexible polyimide (PI) dielectric substrate to form a GAF-based wing-conformal antenna configuration with a low-profile, lightweight, and easily conformal performance. Second, a GAF conformal antenna element is developed by combining a dipole antenna with a directive and reflective frequency selective surface (FSS), achieving effective control of the beam and stable directional radiation at 2.4 GHz. Full-wave simulations using CST Studio Suite show that the directive FSS narrows the feed beam, whereas the reflective FSS redirects and narrows the H-plane radiation. The simulated results show that the integrated wing-conformal antenna operates over 2.19–2.65 GHz and achieves a gain of 4.65 dBi at 2.4 GHz. The measurement results indicate that the GAF conformal antenna and 1 × 4 GAF conformal array antenna shows measured reflection coefficients below 10 dB at 2.4 GHz and effective adjacent-element isolation. In addition, simulated results indicate that the GAF array antenna can perform beam scanning within the ±40° range, verifying the beam-control capability of this structure for UAV forward communication. Overall, this work highlights the feasibility of using GAF as a conductive material for both a high-efficiency radiator and an FSS beamforming structure, offering a practical material and design approach for lightweight, low-profile, and wing-conformal airborne array antennas.
