摘要The propagation and dynamical evolution of a scalar field in the background of a (2+1)-dimensional Einstein–Power–Maxwell (EPM) black hole are studied. We obtain an analytical expression for the greybody factor, which shows that the greybody factor increases as the electric charge increases and approaches unity for large frequencies. We also find the quasinormal modes of the black hole, which tell us that the EPM spacetime is very stable.
