Extremal Transmission and Beating Effect of Acoustic Waves in Two-Dimensional Sonic Crystals
Extremal Transmission and Beating Effect of Acoustic Waves in Two-Dimensional Sonic Crystals
The extremal transmission of the acoustic wave near the Dirac point in two-dimensional (2D) sonic crystals, being inversely proportional to the thickness of sample, has been demonstrated experimentally for the first time. Some unusual beating effects have been observed experimentally, when the acoustic pulse transports through the 2D sonic crystal …
