Dispersive Waves Propagating along a Surface Fracture
Significant work in the past few decades has lead to a well developed understanding of seismic wave propagation in fractured media. However, previous research has focused on fractures within rock as opposed to fractures at the surface of a rock. A theoretical and experimental study was performed to examine seismic wave propagation along a fracture at the surface, i.e., along the intersection of...
متن کاملIonopause-like density gradients in the Martian ionosphere: A first look with MAVEN
For unmagnetized planets, the top of the ionosphere is oftenmarked by a sharp change in electron density and other plasma properties, called an ionopause. Here we present a statistical study of dayside ionopause-like density gradients observed in 54% of ion density profiles from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission spacecraft at Mars. Prior studies of the Martian ionopause...
متن کاملEmbedded Rayleigh–Bloch surface waves along periodic rectangular arrays
In this paper, surface waves in the presence of an infinite periodic array of obstacles of rectangular cross-section are considered. Rayleigh–Bloch surface waves are described by a localised wave motion which does not propagate energy away from the array. The periodicity of the array implies the existence of a cut-off frequency below which Rayleigh–Bloch surface waves may be sought. Such soluti...
متن کاملSurface Waves along a Single-Negative and Double
Existence of a surface wave along the boundary between the semi-infinite materials, one of which is a free-space and the other is a material with either negative permeability or negative permittivity, is presented theoretically in this paper. Surface waves exist in only limited combination of negative and positive sign of the material parameters. In addition, by analyzing the surface wave in a ...
