- We present numerical results of a temporal evolution of impulsively excited magnetosonic waves in a solar coronal loop that is approximated by a set of two straight plasma slabs of mass density enhancement. Numerical simulations reveal that shapes of wavelet spectra of time signatures of these waves depend on a distance between the strands and on a position of the initial pulse. We find that with a distance growing between these strands short period waves contribute more while long period waves contribute less to the wavelet spectra. We demonstrate that a presence of the second parallel strand affects considerably wave propagation in comparison to one strand alone. We find out that the initial pulse triggers a packet of propagating waves among witch sausage and kink modes are present simultaneously.
