The Wave Mechanics and Metamaterials Laboratory develops novel light-weight materials and structures for protection from undesirable vibrations and noise in Aerospace Industry. All research activities in the laboratory are supervised by Asst. Prof. Pavel I. Galich.
Currently, the fundamental challenge is to understand how elastic waves propagating in magnetoelastic solids are affected by high magnetic fields (> 1 T), and then to employ this knowledge for the creation of the adaptive acoustic metamaterials and devices such as silencers, vibration dampers, acoustic diodes, unidirectional reflectors, etc.
Experimental capabilities
Waves in solids
We can perform transmission loss measurements for longitudinal [pressure] and transverse [shear] waves for a wide range of ultrasonic frequencies (i.e. 0.02-5 MHz).
Waves in air
We can determine sound absorption coefficient, surface impedance, and transmission loss, according to ISO or ASTM for a wide range of frequencies (i.e. 0.05–6.4 kHz).
