Abstract In the present paper, a new partial differential equation has been obtained to describe the Rossby solitary waves with complete Coriolis force by employing multi-scale analysis and perturbation method, we call it combined ZK-mZK equation.The equation can reflect the propagation of Rossby waves on the plane and is more appropriate for the r
Abstract Topological photonic crystals, which offer topologically protected and back-scattering-immune transport channels, have recently gained significant attention for both scientific and practical reasons.Although most current studies focus on dielectric materials with weak dispersions, this study focuses on topological phases in dispersive mate
