Spectral-domain Formulation of Electro- Magnetic Scattering from Circular Cylin- Ders Located near Periodic Cylinder Array
This paper considers a periodic circular cylinder array with additional cylinders and formulates the electromagnetic scattering problem of this imperfectly periodic structure. Generally, the fields in imperfectly periodic structures have continuous spectra, and the spectral-domain approaches require appropriate discretization schemes in many cases. The present formulation is based on the pseudo...
متن کاملElectromagnetic Scattering from Periodic Arrays of Two Circular Cylinders per Unit Cell
An efficient and accurate method to the problem of planewave scattering from periodic arrays of two circular-cylinders per unit cell is presented. The scattered fields are calculated using the lattice sums characterizing a periodic arrangement of scatterers and the aggregate T -matrix for the isolated two-cylinders system in free space. The cylinders may be of dielectric, perfect conductor, or ...
متن کاملElectromagnetic 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...
متن کاملCoordinate transformation formulation of electromagnetic scattering from imperfectly periodic surfaces.
This paper considers the electromagnetic scattering problem of periodically corrugated surface with local imperfection of structural periodicity, and presents a formulation based on the coordinate transformation method (C-method). The C-method is originally developed to analyze the plane-wave scattering from perfectly periodic structures, and uses the pseudo-periodic property of the fields. The...
متن کاملElectromagnetic Dyadic Green's Functions in Spectral Domain for Multilayered Cylinders
Dyadic Green's function (DGF), as an electromagnetic response of dielectric medium or the field contributed due to a delta source, is quite useful to solve electromagnetic boundary-value problems. DGFs for multilayered structures are of particular interest to many engineers and scientists because of its better accuracy in modelling practical problems. Cylindrically multilayered medium is one of...
