The writing of indentations in piezoelectric resonators was achieved by applying large amplitude oscillation, which introduced plastic deformations. The reading out of indentations was attained in the resonant oscillation space. They were described with the same notion as the hole burning phenomena. The detected indentation figures were well described the… CONTINUE READING
