A novel grating coupling scheme with simultaneously broadband and wide-angle efficiency for unidirectionally coupling freely propagating light into a silicon waveguide is proposed and theoretically investigated.The coupling structure is composed of two cascaded subgratings with proper spectral and angular intervals.A semi-analytical theory based on

We analyze the thermodynamic potentials and Joule-Thomson adiabatic expansion of a nonlinear electrodynamics charged AdS Ramekin black hole.The negative cosmological constant is designated as thermodynamic pressure, while the geometrical mass is regarded as the enthalpy.In this study, we demonstrate the analogy between thermodynamic phase transitio
