Transmission Eigenvalues
The scattering of a time-harmonic plane wave in an inhomogeneous medium is modeled by the scattering problem for the Helmholtz equation. A transmission eigenvalue is a wavenumber at which the scattering operator has a non-trivial kernel or cokernel. Because many sampling methods for locating scatterers succeed only at wavenumbers that are not transmission eigenvalues, they have been studied for...
متن کاملSimulations of transport in one dimension
Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...
متن کاملNotes on Transmission Eigenvalues
Here k = ω/co is the wave number, ω denotes the frequency of excitation, S2 = {x ∈ R3, |x| = 1} is the unit sphere in R3, and co is such that its real and imaginary parts are respectively <(co)> 0 and =(co)60. The support ofD is assumed to be such that R3 \D is connected, and that ∂D is of Lipschitz type. As a canonical example of the scattering by a penetrable obstacle, consider next the case ...
متن کاملEnergy band correction due to one dimension tension in phosphorene
Among graphene-like family, phosphorene is a typical semiconducting layered material, which can also be a superconductor in low temperature. Applying pressure or tension on phosphorene lattice results in changing the hopping terms, which change the energy bands of the material. In this research we use the tight-binding Hamiltonian, including relevant hopping terms, to calculate energy bands of ...
