We study quasinormal modes and scattering properties via calculation of the $S$ matrix for scalar and electromagnetic fields propagating in the background of spherically symmetric and axially symmetric traversable Lorentzian wormholes of a generic shape. Such wormholes are described by the general Morris-Thorne ansatz. The properties of quasinormal ringing and scattering are shown to be determined by the behavior of the wormhole's shape function $b(r)$ and shift factor $\ensuremath{\Phi}(r… 52 Citations ## Figures from this paper Revisiting a family of wormholes: geometry, matter, scalar quasinormal modes and echoes • Physics The European Physical Journal C • 2020 We revisit a family of ultra-static Lorentzian wormholes which includes Ellis–Bronnikov spacetime as a special case.

It is generally agreed that the acceleration of the Universe can best be explained by the presence of dark or phantom energy. The equation of state of the latter shows that the null energy condition
