Transient-state response of wave propagation in magneto-electro-elastic square column

This is a continued work in studying the wave propagation in a magneto-electro-elastic square column (MEESC). Based on the analytic dispersive equation, group velocity equation and steady-state response obtained in our previous paper ‘Steady-state response of the wave propagation in a magneto-electro-elastic square column’ published in CME, the dynamical behavior of MEESC was studied in this paper. The unlimited column is an open system. The transient-state response in the open system subjected by arbitrary external fields was derived when the propagating wave pursuing method was introduced.
