Complete confinement and extraordinary propagation of Dyakonov-like polaritons in hBN

•Found two highly confined Dyakonov-like polaritons.•Saw remarkable walk-off angle.•Dyakonov-like polaritons are very easily excited.•Energy-flux density of polariton is highly located at the surface. Two Dyakonov-like polaritons (DLPs) were found in the hexagonal boron nitride (hBN). DLP-I lies in...
