a The Poynting vector \( {\overrightarrow{P}}_{R+}^D\equiv {P}_{r,R+}^D{\widehat{e}}_r+{P}_{\theta, R+}^D{\widehat{e}}_{\theta } \) on the cross-sectional plane evaluated at ρ = 1+ with increasing 0 ≤ m ∈ ℤ. b An imperfect reflection of an outgoing wave for a given incoming wave. c The radial profile of the circumferentially integrated \( \rho {P}_r^D\left(\rho \right) \)
