Multiple scattering from gyrotropic bianisotropic cylinders of arbitrary cross sections using the modeling technique.
Based on the principle of the equivolumetric model, the multiple scattering from two-dimensional composite gyrotropic bianisotropic cylinders (GBC's) possessing a certain magnetic group of symmetry is studied by using the indirect modeling technique. At first, a mathematical formulation for the problem is carried out and its solution expressed in terms of a system of simultaneous linear equatio...
متن کاملModelling of water wave interaction with multiple cylinders of arbitrary shape
7 This paper describes the development of an efficient numerical model, namely scaled bound8 ary finite-element method (SBFEM) for linear waves interaction with cylindrical structures 9 of arbitrary shapes. The two-dimensional Helmholtz equation is firstly weakened in the cir10 cumferential direction, so that the governing partial differential equation is transformed to 11 an ordinary matrix di...

ments are usually obtained one slice at a time, where each slice is a 2D array of scalar values corresponding to meaIn computed tomography, magnetic resonance imaging and ultrasound imaging, reconstruction of the 3D object from the surements distributed over a plane passing through the 2D scalar-valued slices obtained by the imaging system is diffiobject. The set of planes generating the slices...
متن کاملCross 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...
متن کاملThermal Development for Ducts of Arbitrary Cross Sections by Boundary-Fitted Coordinate Transformation Method
The non-orthogonal boundary-fitted coordinate transformation method is applied to the solution of steady three-dimensional momentum and energy equations in laminar flow to obtain temperature field and Nusselt numbers in the thermal entry region of straight ducts of different cross sectional geometries. The conservation equations originally written in Cartesian coordinates are parabolized in the...
