Cross sections for extinction of tilted infinite circular cylinders.

It follows that Kerker's equations (6.1.46) and (6.1.47) should be deleted, and the quantities C n e x t and C22 ext should be replaced by C1 ex t and C2 ex t . Note that the forwardscattering (θ = 0) wave as well as the backscattering wave from tilted infinite cylinders is not de­ polarized, an effect which is well known in the case of spheres. But in contradiction to the spheres, the followin...

Bilateral symmetry breaking in nonlinear circular cylinders.

Symmetry breaking is a common phenomenon in nonlinear systems, it refers to the existence of solutions that do not preserve the original symmetries of the underlying system. In nonlinear optics, symmetry breaking has been previously investigated in a number of systems, usually based on simplified model equations or temporal coupled mode theories. In this paper, we analyze the scattering of an i...

Parallel 3D Computation of Unsteady Flows Around Circular Cylinders

Lower Mode Response of Circular Cylinders in Cross-Flow

Transverse amplitude responses ofa circular cylinder in cross-flow were determined as a function of reduced velocities for a variety of spring constants and damping coefficients. Maxima were found at reduced velocities of 5 and 16, and were of comparable amplitude. The first resonance, designated the "fundamental mode, " was due to normal vortex street excitation of the spring-mass system. The ...
