Taylor Expansion and Discretization Errors in Gaussian Beam Superposition
The Gaussian beam superposition method is an asymptotic method for computing high frequency wave fields in smoothly varying inhomogeneous media. In this paper we study the accuracy of the Gaussian beam superposition method and derive error estimates related to the discretization of the superposition integral and the Taylor expansion of the phase and amplitude off the center of the beam. We show...
متن کاملQuasi-optical Beam Waveguide Analysis Using Gaussian Beam Expansion
For reflector antennas and mirrors with diameters < 50 ? Physical Optics (PO) and the Physical Theory of Diffraction (PTD) are very fast and accurate calculation methods for determining the scattered fields. In optics where the diameter of the mirrors >> 1000 ? ray tracing methods are sufficient means of determining the scattered fields. However, in the Quasi-optical range in between these wave...
متن کاملNonautonomous Discrete Dynamics: Discretization and Taylor Approximation
In this talk, we consider a class of nonautonomous difference equations (recursions) possessing an attractive invariant manifold in the extended state space. It is our aim to study the behavior of this manifold, as well as of its corresponding asymptotic phase under perturbation. Our framework is sufficiently general to include discrete counterparts of (center-)unstable and inertial manifolds. ...

Background: Inclusion of inhomogeneity corrections in intensity modulated small fields always makes conformal irradiation of lung tumor very complicated in accurate dose delivery.Objective: In the present study, the performance of five algorithms via Monte Carlo, Pencil Beam, Convolution, Fast Superposition and Superposition were evaluated in lung cancer Intensity Modulated Radiotherapy plannin...
متن کاملTaylor Expansion for the Entropy Rate of Hidden Markov Chains
We study the entropy rate of a hidden Markov process, defined by observing the output of a symmetric channel whose input is a first order Markov process. Although this definition is very simple, obtaining the exact amount of entropy rate in calculation is an open problem. We introduce some probability matrices based on Markov chain's and channel's parameters. Then, we try to obtain an estimate ...
