Propagation of elastic surface waves along a cylindrical cavity of arbitrary cross section
— The propagation of elastic surface waves, guided by the free surface of an infinitely long cylinder, of arbitrary cross section, is formulated as on eigenvalue problem, for an unbounded self adjoint operator. We prove the existence of a hierarchy of guided modes. Two of them propagate for any value of the wave number, whereas all of the others only exist beyond a cut-off wave number. For any ...
متن کاملPropagation of elastic waves through a lattice of cylindrical cavities
We consider the wave propagation through a doubly-periodic array of cavity cylinders in an isotropic elastic medium using the method of matched asymptotic expansions, based on the assumptions that the scatterer size is much smaller than both the wavelength and the array periodicity. There is no restriction on the wavelength relative to the array periodicity, and hence the method yields explicit...
متن کاملPropagation of Torsional Waves in a Waveguide of Arbitrary Cross- section Immersed in a Fluid
A Semi-Analytical Finite Element (SAFE) method is developed to model accurately the propagation velocity and leakage of guided waves along an immersed waveguide with arbitrary non-circular cross-section. Thus an accurate inverse model is provided to measure the density of the fluid by measuring the change of the torsional wave speed. Experimental results obtained with a rectangular bar in a ran...
متن کاملElectromagnetic analysis of cylindrical cloaks of an arbitrary cross section.
We extend the design of radially symmetric invisibility cloaks through transformation optics as proposed by Pendry et al. [Science 312, 1780 (2006)] to coated cylinders of an arbitrary cross section. The validity of our Fourier-based approach is confirmed by both analytical and numerical results for a cloak displaying a non-convex cross section of varying thickness. In the former case, we evalu...
متن کاملDisturbed critical surface waves in a channel of arbitrary cross section
Long waves in a current of an inviscid fluid of constant density flowing through a channel ofarbitrary cross section under disturbances of pressure distribution on free surface and obstructors on thewall of the channel are considered. The first order asymptotic approximation of the elevation of the freesurface satisfies a forced Korteweg-de Vries equation when the current is nea...
