Special Issue Information

Dear Colleagues,

With the continuous progress of nanofabrication technologies, metasurfaces have become an important platform for multi-dimensional optical field modulation, providing versatile control over phase, polarization, amplitude, and frequency. These capabilities have substantially extended their applications in photonics such as augmented reality, virtual reality, polarization detection, polarization imaging, structured light, and so on. This Special Issue emphasizes recent advances in optical applications enabled by metasurfaces, particularly those that transcend the limitations of conventional diffractive components. These advances enable the realization of lightweight, miniaturized, and integrated optical devices, further advancing the field of metasurface-based photonic integration.

We invite original research articles and reviews. Research areas may include (but are not limited to) the following:

  • Multidimensional optical modulation.
  • Metalens and light-field imaging.
  • Structural color based on metasurface.
  • Polarimetry and polarization imaging.
  • Applications of metasurfaces in multispectral/hyperspectral imaging, biosensing, augmented/virtual reality, and structural light.

We look forward to receiving your contributions.

This paper introduces a vanadium dioxide-integrated broadband metamaterial absorber designed for the terahertz frequency range. The simulation results for the proposed structure demonstrate a wide 90% absorption bandwidth of 8.23 THz, corresponding to a fractional bandwidth of 89.5%. By leveraging the phase-transition properties of VO2, the absorber demonstrated dynamic adjustability by modulating the absorption from 3% to 98.74%. The absorption mechanism was analyzed through the impedance matching theory and electromagnetic field distributions, confirming the role of magnetic resonance and interference. Furthermore, machine learning algorithms, specifically Linear Regression, Support Vector Regression, and Random Forest (RF), were applied to accelerate the design process and optimize the structural parameters. Among these, the RF model demonstrated superior prediction accuracy. The machine learning-assisted optimization successfully extended the effective absorption bandwidth to 9 THz, representing an improvement by 9.4% compared to the traditional optimization methods. These results validate the efficacy of combining electromagnetic simulation with data-driven techniques for advanced metamaterial design. Full article
