We discuss the computation of the band structure of plate waves using the plane wave expansion (PWE) method. This method is generally used to formulate eigenvalue problems to compute dispersion ...

We propose a method to invert surface wave dispersion data directly for 3-D variations of shear wave speed, that is, without the intermediate step of phase or group velocity maps, using ...

2.3 Analysis methods for the surface wave 2.3.1 The F-J method for multimodal dispersion curves extraction The F-J method is an array-based surface wave analysis method designed for extracting ...

The code for calculating plasma wave dispersion relation. Each branch is used to solve one kind of problem, such as parallel waves, perpendicular waves, CMA diagram and so on.

SIAM Journal on Applied Mathematics, Vol. 77, No. 6 (2017), pp. 2119-2135 (17 pages) We study waves governed by the planar Helmholtz equation, propagating in an infinite lattice of subwavelength ...

The CU Boulder Applied Mathematics Department's Dispersive Hydrodynamics Laboratory investigates nonlinear wave phenomena in fluid-like systems. The key features of systems explored include ...

The surface wave dispersion curves can be identified by the maximum of I (c, ω). For the observed seismic data, C (r, ω) is the seismic trace with offset r, so a seismic array is needed to calculate I ...
