Differences between sound scattering by weakly scattering spheres and finite-length cylinders with applications to sound scattering by zooplankton.

A modeling study was conducted to determine the conditions under which fluidlike zooplankton of the same volume but different shapes (spherical/cylindrical) have similar or dramatically different scattering properties. Models of sound scattering by weakly scattering spheres and cylinders of finite length used in this analysis were either taken from other papers or derived and herein adapted for...

Best Bells for Scattering by Pec Cylinders

Application of the local bell-modulated cosine bases of Coifman and Meyer to the problem of scattering by PEC cylinders leads to a sparse Method of Moments interaction matrix. To optimize the sparsity representation it is imperative to find bell functions with nice Fourier radiation properties. Here we pose the problem of bell optimization in terms of Chebyshev’s inequality, resulting in a fami...

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 ...

Electromagnetic Scattering from Multiple Cylinders

During the last several decades, electromagnetic scattering from multiple cylinders has been an active research topic of in many areas, such as microwave remote sensing, theory of photonic crystals, atmospheric sciences, and so on. Rigorous theoretical treatment is therefore of critical importance. A large body of available studies in the literature concerns with two dimensional scattering, suc...
