Wave transport for a scalar model of the Love waves
نویسندگان
چکیده
We study transport for a scalar model of Love waves. These waves arise in the propagation of seismic waves whose energy is concentrated in the vicinity of the earth surface. We derive radiative transfer equations from rst principles for the angularly resolved energy density of the Love waves in a simpliied acoustic model. We consider a rough top surface with weak uctuations at the scale of the wavelength. The transport equation accounts for the multiple scattering of the Love waves and their scattering into volume waves. We also analyze a diiusive regime when energy is universally distributed over various modes of the Love waves.

Study of Love Waves in a Clamped Viscoelastic Medium with Irregular Boundaries
A mathematical model is presented to investigate the effects of sandiness, irregular boundary interfaces, heterogeneity and viscoelasticity on the phase velocity of Love waves. Geometry of the problem is consisting of an initially stressed viscoelastic layer with corrugated irregular boundaries, which is sandwiched between heterogeneous orthotropic semi-infinite half-space with initial stress a...
متن کاملGeneration of Love Wave in a Media with Temperature Dependent Properties Over a Heterogeneous Substratum
The present paper deals with the generation of Love waves in a layer of finite thickness over an initially stressed heterogeneous semi-infinite media. The rigidity and density of the layer are functions of temperature, i.e. they are temperature dependent. The lower substratum is an initially stressed medium and its rigidity and density vary linearly with the depth. The frequency relation of Lo...
