We show that when the scatterers are placed regularly in the perimeter of a circumference these structures form a resonator which quality factor grows up exponentially with the number of scatterers. Numerical experiments are performed for elastic waves in thin elastic plates and acoustic waves trapped atop a metasurface, and an experimental validation of the latter is also presented.Show less >
