Attenuation of the Surface Acoustic Soliton by Surface Roughness

Based on the theory of the surface acoustic (SA) soliton presented previously, we investigate the attenuation of the SA soliton in the presence of surface roughness. With the aid of the reductive perturbation method, we have finally obtained a nonlinear Schrödinger equation with a damping term whose...

Description
Summary:Based on the theory of the surface acoustic (SA) soliton presented previously, we investigate the attenuation of the SA soliton in the presence of surface roughness. With the aid of the reductive perturbation method, we have finally obtained a nonlinear Schrödinger equation with a damping term whose coefficient involves the attenuation rate of the surface-phonons due to the surface roughness.
