On uniqueness in electromagnetic scattering from biperiodic structures

A second scheme is associated with a decentered shock-capturing–type space discretization: the II scheme for the viscous linearized Euler–Poisson (LVEP) system (see section 3.3)..

We give a variational formulation for the electromagnetic scattering problem in a suitable Sobolev space of functions defined in an unbounded domain containing the

We desenbe a simple variational method for finding weak « quasipenodic » solutions to Maxwell's équations in such a structure Our formulation is simple and computationally

Since boundary integral equations are a clas- sical tool to solve electromagnetic scattering problems, we study the shape differentiability properties of the standard

Under the realistic hypothesis of discontinuity of the electric permittivity across the boundary of a dielectric, we first derived two integral formulations: a volume integral

One knows that such boundary integral formulations of the Maxwell equations are not uniquely solvable when the exterior wave number is an eigenvalue of an associated interior
