    • In order to efficiently excite modes with different spatial symmetries we apply to the central dot of the array a field pulse perpendicular to the sample plane. It is obtained as the sum of an uniform pulse and a pulse with an odd symmetry with respect to the direction defined by the in-plane external field H0

    • In the case of edge modes the choice of different ground states for the dynamic simulation (i.e., C and S state or flower state) could result in quite different outcomes for the calculated frequency and spatial profile. The mode profiles and power spectra showed in this work have been all obtained using a flower ground state, both for the isolated dot and the 3×3 array of squares
