Abstract
A hybrid finite element/boundary element technique (FEM/BEM) is presented for the analysis of plane wave scattering from an axially corrugated cylinder of arbitrary geometric and material parameters. Inside the periodic structure a cylinder of infinite length composed of a piecewise uniform isotropic medium moving uniformly in the axial direction is also considered. Covariant-projection edge elements are employed in the inhomogeneous region of the unit cell to solve the Maxwell-Minkowski equations, whilst the scattered field is expanded in terms of cylindrical Floquet harmonics. Numerical results, for both TE z and TMz polarised incident fields, are presented and validated as far as was possibleI documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
