Sensitivity analysis results of the defect band frequencies that correspond to the in-phase and out-of-phase monopole-like defect modes in terms of material properties and geometric variation. a Effects of the mass density of the aluminum plate, ranging from 2600 to 2800 kg/m3. b Effects of Young’s modulus of the aluminum plate, ranging from 66 to 74 GPa. c Effects of the diameter of the circular hole, ranging from 29.50 to 30.50 mm. d Effects of the thickness of the unit cell, ranging from 1.90 to 2.10 mm
