Eigenvalue problems with sign-changing coefficients
We consider a class of eigenvalue problems involving coefficients changing sign on the domain of interest. We describe the main spectral properties of these problems according to the features of the coefficients. Then, under some assumptions on the mesh, we explain how one can use classical finite element methods to approximate the spectrum as well as the eigenfunctions while avoiding spurious ...
متن کاملSuperlinear elliptic problems with sign changing coefficients
Via variational methods, we study multiplicity of solutions for the problem −∆u = λb(x)|u|q−2u + a u + g(x, u) in Ω , u = 0 on ∂Ω . where a simple example for g(x, u) is |u|p−2u; here a, λ are real parameters, 1 < q < 2 < p ≤ 2∗ and b(x) is a function in a suitable space L. We obtain a class of sign changing coefficients b(x) for which two non-negative solutions exist for any λ > 0, and a...
متن کاملElectromagnetic scattering by periodic structures with sign-changing coefficients
We analyze well-posedness of a scattering problem of time-harmonic electromagnetic waves by periodic structures with sign-changing coefficients. Transmission problems for Maxwell’s equations with sign-changing coefficients in bounded domains have been recently studied by Bonnet-Ben Dhia and co-workers in the so-called T -coercivity framework. In this article we generalize such framework for per...
متن کاملHomogenization of Periodically Varying Coefficients in Electromagnetic Materials
In this paper we employ the periodic unfolding method for simulating the electromagnetic field in a composite material exhibiting heterogeneous microstructures which are described by spatially periodic parameters. We consider cell problems to calculate the effective parameters for a Debye dielectric medium in the cases of circular and square microstructures in two dimensions. We assume that the...
متن کاملHomogenization of ferromagnetic materials
In these notes we describe the homogenzation theory for ferromagnetic materials. A new phenomenon arises, in particular to take into account the geometric constraint that the magnetization is locally saturated.
