“…The triangular lattice and honeycomb lattice are two important candidates for the fabrication of PCs. They are not only easy to manufacture for customizable and large-scale production but also exhibit extraordinary optical properties and rich applications [30][31][32][33][34][35][36][37]. The shape and size of the scatter elements have a great influence on the positions and widths of the band gaps [38].…”

We demonstrate a method to generate tunable triangular and honeycomb plasma structures via dielectric barrier discharge with uniquely designed mesh-liquid electrodes. A rapid reconfiguration between the triangular lattice and honeycomb lattice has been realized. Novel structures comprised of triangular plasma elements have been observed and a robust angular reorientation of the triangular plasma elements with θ = π / 3 is suggested. An active control on the geometrical shape, size and angular orientation of the plasma elements has been achieved. Moreover, the formation mechanism of different plasma structures is studied by spatial-temporal resolved measurements using a high-speed camera. The photonic band diagrams of the plasma structures are calculated by use of finite element method and two large omnidirectional band gaps have been obtained for honeycomb lattices, demonstrating that such plasma structures can be potentially used as plasma photonic crystals to manipulate the propagation of microwaves. The results may offer new strategies for engineering the band gaps and provide enlightenments on designing new types of 2D and possibly 3D metamaterials in other fields.

“…Based on polyaniline and GaAs, a nonlinear THz modulator was designed by using line defect and point defect. [ 86 ] The modulator was designed by a 2D photonic crystal composed of a hexagonal air hole array, and silicon was used as the substrate material. The structure consisted of two‐line defects as waveguides and a single point defect as a microcavity along the Z direction.…”

5G communication has begun commercial deployment. To maintain the sustainability and competitiveness of wireless communication systems, various industries and academic institutions around the globe are designing the framework for 6G communications. Compared with the previous generations of communication systems, 6G will be revolutionary, with unprecedented requirements in data transmission rates, delays, and global coverage. Many promising technologies in 6G systems, including terahertz communication, ultra‐large‐scale antenna arrays, large‐scale intelligent surfaces, quantum communication, and computing, have differing material requirements compared with previous systems. With the development of materials science, an increasing number of new materials will play important roles in 6G communications. Herein, the high demand of 6G systems is introduced first in this review, and recent advances of new materials having a broad variety of applications with great potential in 6G systems are systematically summarized. Perspectives on the research areas that require special attention are also presented.
