Theoretical mass sensitivity of Love wave and layer guided acoustic plate mode sensors [PDF]

, 2002
A model for the mass sensitivity of Love wave and layer guided shear horizontal acoustic plate mode (SH–APM) sensors is developed by considering the propagation of shear horizontally polarized acoustic waves in a three layer system. A dispersion equation

Surface waves and surface wave devices in atmospheric acoustics [PDF]

The Journal of the Acoustical Society of America, 1990
Surface waves exist above porous grounds when the surface can influence the airborne particle velocity near the ground and reduce the phase velocity of sound waves in air at the surface, thereby trapping some of the energy to remain near the surface as the wave propagates. The experimental evidence for the existence of an acoustic surface wave has been
