Electromagnetic Scattering of Two- Dimensional Electronic Systems

Electromagnetic Scattering Analysis Using the Two-dimensional Mrfd Formulation

Recently developed multiresolution frequency domain (MRFD) technique is applied to two-dimensional electromagnetic scattering problems. Scattered field formulation and perfectly matched layer is implemented into the MRFD formulation. Far field distributions of dielectric and perfectly electric conductor (PEC) bodies are calculated and bistatic echo widths of these structures are presented. Good...

Three - Dimensional Electromagnetic Inverse Scattering

A numerical algorithm for the reconstruction of the permittivity of a three-dimensional penetrable object from scattering data is presented. The reconstruction algorithm is based on the local shape function method (LSF) combined with the conjugate gradient method with FFT (CGFFT). The nonlinearity due to the multiple scattering is accounted for in an iterative minimization scheme. Numerical exa...

Localization of electromagnetic waves in two-dimensional disordered systems.

We calculate the average transmission for sand p-polarized electromagnetic ~EM! waves and consequently the localization length of two-dimensional ~2D! disordered systems which are periodic on the average; the periodic systems form a square lattice consisting of infinitely long cylinders parallel to each other and embedded in a different dielectric medium. In particular, we study the dependence ...

An analysis of electromagnetic scattering from finite-width strips

Electron-electron scattering in linear transport in two-dimensional systems.

We describe a method for numerically incorporating electron–electron scattering in quantum wells for small deviations of the distribution function from equilibrium, within the framework of the Boltzmann equation. For a given temperature T and density n, a symmetric matrix needs to be evaluated only once, and henceforth it can be used to describe electron–electron scattering in any Boltzmann equ...
