“…These defect modes are strongly localized around the point defect: once the wave is inside the defect, it is trapped as the borders of the defect act as perfect mirrors for waves with frequencies in the BG. Localization depends on several parameters as for example the size of the point defect but, in finite periodic structures, the strength of sound localization also depends on the size of the structure around the defect [Wu09a,Wu09b] due to the exponential decay of the outgoing wave.…”
