(a) The relation between the incident angle and reflected angle when k_s = −0.762. The red dots are data obtained from the full-wave simulation. The blue solid line indicates the anomalous reflection state , the cyan and green solid lines represent the allowed apparent negative reflection states and respectively. (b) Calculated scattered acoustic field under the plane acoustic wave illumination of different incident angles.
