Lieb lattice has been proven to host various extraordinary properties due its unique Dirac-flat band structure. However, the realization of tunable lattices with controllable configurations still remains a significant challenge. We demonstrate first robust and tailorable plasma in dielectric barrier discharges by use uniquely designed mesh-water electrodes. Fast reconfiguration between square lattice, superlattices achieved wide range discharge parameters even ambient air. Active control...
Abstract 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 lattice has been realized.

Abstract 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 simple lattice, superlattice, and honeycomb-snowflake is achieved. A dynamic control on sizes center scattering elements has been realized. phenomenological activator-inhibitor reaction diffusion model established to demonstrate formation reconstruction superlattice. The simulations...
Abstract Archimedean photonic crystal has become a research area of great interest due to its various unique properties. Here, we experimentally demonstrate the realization reconfigurable (4, 6 2 ) and 8 plasma crystals (APPCs) by use dielectric barrier discharges in air. Dynamical control on both macrostructures including lattice symmetry orientation, microstructures fine structures scattering elements been achieved. The formation mechanisms APPCs are studied time-resolved measurements...
