Perturbation theory for anisotropic dielectric interfaces, and application to subpixel smoothing of discretized numerical methods.
We derive a correct first-order perturbation theory in electromagnetism for cases where an interface between two anisotropic dielectric materials is slightly shifted. Most previous perturbative methods give incorrect results for this case, even to lowest order, because of the complicated discontinuous boundary conditions on the electric field at such an interface. Our final expression is simply...
متن کاملPerturbation Theory for Scattering from Multilayers with Randomly Rough Fractal Interfaces: Remote Sensing Applications
A general, approximate perturbation method, able to provide closed-form expressions of scattering from a layered structure with an arbitrary number of rough interfaces, has been recently developed. Such a method provides a unique tool for the characterization of radar response patterns of natural rough multilayers. In order to show that, here, for the first time in a journal paper, we describe ...
متن کاملPerturbation theory for confined systems
We discuss the application of perturbation theory to a system of particles confined in a spherical box. A simple argument shows that the particles behave almost independently in sufficiently strong confinement. We choose the helium atom with a moving nucleus as a particular example and compare results of first order with those for the nucleus clamped at the center of the box. We provide a suita...
متن کاملPerturbation Theory for the SingularValue
abstract The singular value decomposition has a number of applications in digital signal processing. However, the the decomposition must be computed from a matrix consisting of both signal and noise. It is therefore important to be able to assess the eeects of the noise on the singular values and singular vectors | a problem in classical perturbation theory. In this paper we survey the perturba...
متن کاملPerturbation theory for gap solitons
The system of coupled nonlinear evolution equations describing gap solitons is shown to be approximately equivalent in the neighborhood of the soliton solution to the massive Thirring model. The equivalence is then used for construction of the perturbation theory for gap solitons based on the RiemannHilbert problem. The value of deviation of the initial condition from the gap soliton shape serv...
