“…The integration of plasmas leads to advantageous properties for PPCs, such as dynamical tunability [14], negative refraction [15], and rapid reconfiguration [16]. Applications of PPCs in plasma stealth aircraft, microwave filter, multichannel communication, and highly sensitive sensors have been proposed [17][18][19][20][21][22][23]. Dielectric barrier discharge (DBD) is one of the most significant systems to realize PPCs.…”

We present the experimental realization of tunable honeycomb superlattice plasma photonic crystals (PPCs) in dielectric barrier discharge by utilizing mesh-liquid electrodes. Fast reconfiguration among the simple honeycomb lattice, honeycomb superlattice, and honeycomb-snowflake superlattice is achieved. A dynamic control on the sizes of center scattering elements in the honeycomb superlattice has been realized. A phenomenological activator-inhibitor reaction diffusion model is established to demonstrate the formation and transition of the honeycomb superlattice. The simulations reproduce well the experimental observations. The photonic band diagrams of different honeycomb PPCs are studied by using finite element method. The addition of large center elements in the honeycomb superlattice yields remarkable omnidirectional band gaps that are about 2.5 times larger than the simple honeycomb lattice case. We propose an effective scheme to fabricate spatiotemporally controllable honeycomb lattices that enable great improvement in band gap size and dynamic control of microwave radiations for wide applications.

“…The tunability of PPCs can also be performed at relatively high rates limited by the ionization or recombination times of the plasmas. These tunable responses give rise to various potential applications, such as the high-speed switch, microwave filter, path-reconfigurable circulator, highly sensitive sensor and plasma stealth aircraft [3][4][5][6].…”

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.
