Acoustic Metamaterials
Acoustic Metamaterials are engineered structures designed to control sound waves in unconventional ways. Unlike natural materials, their acoustic properties arise from internal structure rather than composition alone. Acoustic metamaterials can manipulate sound propagation, absorption, and direction. They enable phenomena such as negative effective density, sound cloaking, and acoustic band gaps. This field combines wave physics, materials science, and engineering design. Acoustic metamaterials have applications in noise reduction, vibration control, and sound focusing. Their behavior is governed by resonance and periodicity at subwavelength scales. Research in acoustic metamaterials expands the ability to tailor wave–matter interactions. This emerging field demonstrates how structured materials can overcome traditional limits of sound control and open new technological possibilities.
