Abstract :
Calculation and simulation show us that when acoustic wave is incident from real bulk module media to complex bulk module media (or from complex bulk module media to real bulk module media), giant positive or negative lateral shift of reflection wave will occur. When acoustic wave is incident from a complex bulk module media to another complex bulk module media, the giant positive or negative lateral shift will occur too.
