A three-dimensionally periodic dielectric structure with a large complete photonic band gap ~PBG! is presented. The structure is distinguished by a sequence of planar layers, identical except for a horizontal offset, and repeating every three layers to form an fcc lattice. The layers can be thought of as an alternating stack of the two basic two-dimensional ~2D! PBG slab geometries: rods in air...

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 ...

This paper studies constructing advanced effective materials using arrays of circular radially-anisotropic (RA) cylinders. Homogenization of such cylinders is considered in an electrodynamic case based on Mie scattering theory. The homogenization procedure consists of two steps. First, we present an effectively isotropic model for individual cylinders, and second, we discuss the modeling of a l...

Flow and flow-induced vibration of a square array of cylinders are investigated by two-dimensional numerical simulations. Flow past 36 cylinders in an inline arranged square array and 33 cylinders in a staggered arranged square array is firstly simulated, for Re=100 and the spacing ratios of L/D=1.5, 2, 3, 4, 5. Only one vortex street is observed in the wake of the cylinder array when the spaci...
