Special Issue Information

Dear Colleagues,

Optoelectronic materials and devices lie at the heart of modern technological advancements, driving innovations in renewable energy, telecommunications, displays, sensing, and biomedical applications. Recent breakthroughs in material synthesis, nanofabrication, and device engineering have unlocked unprecedented opportunities to enhance performance, sustainability, and scalability. This Special Issue aims to highlight cutting-edge research and interdisciplinary efforts shaping the future of optoelectronics, with a focus on novel materials, advanced device architectures, and emerging applications.

Scope of the Issue:

We invite original research articles, reviews, and perspectives addressing key challenges and opportunities in optoelectronics. Topics include, but are not limited to, the following:

Next-generation materials: perovskites, 2D materials, organic semiconductors, and quantum dots.
Advanced photonic and optoelectronic devices: LEDs, solar cells, photodetectors, lasers, and optical modulators.
Flexible, stretchable, and wearable optoelectronics for healthcare and IoT applications.
Integration of optoelectronic systems with AI-driven technologies and neuromorphic computing.
Novel characterization techniques and theoretical modeling of optoelectronic processes.
Sustainable fabrication methods and recycling strategies for eco-friendly devices.
Metamaterials and metasurfaces, and the related optoelectronic materials and devices.

Abstract
This paper proposes a tri-band wide-angle polarization-insensitive absorber operating in the C-band and Ku-band, based on the design concept of metal–dielectric–metal. The absorber achieves absorption efficiencies of 99.05%, 99.3%, and 97.9% at 4.23 GHz, 7.403 GHz, and 14.813 GHz, respectively. The first two [...] Read more.
This paper proposes a tri-band wide-angle polarization-insensitive absorber operating in the C-band and Ku-band, based on the design concept of metal–dielectric–metal. The absorber achieves absorption efficiencies of 99.05%, 99.3%, and 97.9% at 4.23 GHz, 7.403 GHz, and 14.813 GHz, respectively. The first two absorption frequencies are in the C-band, while the third absorption frequency is in the Ku-band, both of which are commonly used in satellite communication. The designed absorber consists of three differently sized regular hexagonal rings. To analyze the interaction mechanism between the electromagnetic wave and the absorber, we applied the theory of impedance matching and equivalent media to analyze the metamaterial properties of the absorber. In addition, the equivalent circuit model of the absorber has been analyzed. We then determined the existence of coupled electromagnetic resonances between the top and bottom surfaces by analyzing the distribution of the electric field, magnetic field, and surface currents on the absorber. By varying the polarization angle and incident angle of the incoming wave, we found that the absorber exhibits polarization insensitivity and wide-angle absorption characteristics. The TE and TM waves maintain more than 90% absorption efficiency up to incident angles of 50° and 60°, respectively. The absorber’s thickness is 1.07 mm, which is 0.0154 times the wavelength corresponding to the lowest resonant frequency (λ0), and the edge length of the subunit’s regular hexagon is 7.5 mm (0.108λ0), making the absorber sub-wavelength in scale while maintaining its compactness. The proposed absorber operates in the C-band and Ku-band, and can be applied in the field of satellite communications, achieving functions such as electromagnetic shielding and stealth. Full article
