Scattering of Irregular Waves by Vertical Cylinders

Scattering by rings of vertical cylinders

It is 25 years since the publication of “Linton & Evans” [1] on “The interaction of waves with arrays of vertical circular cylinders”; it is their most cited joint work. The paper describes an exact method in which separation of variables and addition theorems are combined, leading to an infinite system of linear algebraic equations. The method itself is much older, and goes back to a paper by ...

Scattering of electromagnetic waves by many thin cylinders

Electromagnetic wave scattering by many parallel infinite cylinders is studied asymptotically as a → 0. Here a is the radius of the cylinders. It is assumed that the points x̂m are distributed so that N (∆) = 1 a R ∆ N(x)dx[1+o(1)], whereN (∆) is the number of points x̂m = (xm1, xm2) in an arbitrary open subset of the plane xoy, the axes of the cylinders are passing through points x̂m, these axes ...

Wave Scattering from Vertical Surface-Piercing Cylinders

This thesis describes new laboratory observations concerning the interaction between a series of steep incident waves and vertical, surface piercing, cylinders. The motivation for the study arose as a result of wave impact damage sustained to the undersides of several concrete gravity-based structures in the northern North Sea. Earlier work, Swan et al., (1997), demonstrated that in the case of...

Nonlinear front evolution of hydrodynamic chemical waves in vertical cylinders

Scattering of electromagnetic waves by many thin cylinders : theory and computational modeling

Electromagnetic (EM) wave scattering by many parallel infinite cylinders is studied asymptotically as a → 0, where a is the radius of the cylinders. It is assumed that the centers of the cylinders x̂m are distributed so that N (∆) = ln( 1 a ) ∫ ∆ N(x)dx[1 + o(1)], where N (∆) is the number of points x̂m = (xm1, xm2) in an arbitrary open subset of the plane xOy, the axes of cylinders are parallel ...
