in this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in fortran. the code was established by combining porous flow and a two-phase model using vof method. modified navier-stokes and k-ε equations implemented to the model to simulate the flow in porous media. cut cell method was modified to simulate fluid t...

We segment seismic data based on the geometric information provided by sparse gaussian wave packet representations. We use this information to for estimates an abundance of candidate curves for the identification of the wave fronts. A graph cut methodology is then employed to reduce the number of curves such that the data is well described by only few wave fronts.

The dispersion equation governing the guided propagation of TE and TM fast wave modes of a circular cylindrical waveguide loaded by metal vanes positioned symmetrically around the wave-guide axis is derived from the exact solution of a homogeneous boundary value problem for Maxwell’s equations. The dispersion equation takes the form of the solvability condition for an infinite system of linear ...

In this paper, by using a quantum hydrodynamic plasma model which incorporates the important quantum statistical pressure and electron diffraction force, we present the corrected plasmon dispersion relation for graphene which includes a k quantum term arising from the collective electron density wave interference effects (which  is integer and constant and k is wave vector). The longitudinal ...

Electron cyclotron heating of high density plasmas is limited due to so-called wave cut-offs. The double mode conversion scheme from O-mode to X-mode and finally to Bernstein mode O-X-B offers the possibility to overcome this limit [1]-[4]. At a particular launching angle, an O-mode wave converts to X-mode at the plasma cut-off. The power transmission function T from Oto X-mode was derived in [...
