A fast method for the radiation analysis of arbitrary oriented planes is presented. It combines an adaptive spectral integration scheme and a recently proposed unequally-spaced fast Laplace transform algorithm [F. Andersson, “Algorithms for Unequal

We propose a method to use an extension of the well-known FDTD algorithm on meshes that would typically imply severe time step size restrictions due to small geometrical details. For this purpose, the Newmark-Beta scheme, which is much less sensitive

We show both analytically and numerically that in quasi-one-dimensional (1D) diffusive samples the distribution of transmission eigenvalue (DTE) displays a phase transition as the asymmetry in the reflections of the sample edges increases. We also sh

We consider generally bianisotropic dielectric media. We consider the linear constitutive relations for bianisotropic media in the Boys-Post representation without spatial dispersion. We propose the high-frequency asymptotic ray series in terms of th

In this work we attempt to overcome the two main limitations of the generic inverse scattering problem: the size and the ill-posed nature of the problem. We use a solver that is based on the discrete Gaussian beam summation method and apply it for th

The changes induced in the near- and far-field scattering by rounding the corners of an illuminated obstacle are discussed as a function of the radius of curvature near such corners. Dirichlet, Neumann or impedance boundary conditions are imposed on

The discrete dipole approximation (DDA) is a variant of volume-integral equation method, which speed largely depends on the iterative solution of system of linear equations. I systematically studied the performance of this solution, varying the parti

Problem of diffraction of electromagnetic waves on a 3D inhomogeneous anisotropic dielectric partially shielded body considered. The problem is reduced to a system of singular integro-differential equations. The operator of the system is treated as a

International audience; We present a new preconditioner for the combined field integral equation (CFIE) that gives rise to a Hermitian, positive definite system of linear equations. Differently from other Calderón strategies, this scheme necessitate

We describe a method to calculate the effective dielectric tensor of a periodic array of dielectric cylinders embedded in a host matrix for transverse electromagnetic waves whose wavelength is much larger than the distance between the cylinders. We r
