Analytical Expressions for the Electromagnetic Dyadic Green’s Function in Graphene and Thin Layers

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Time-harmonic Electromagnetic Fields in Thin Chiral Curved Layers

In this paper, we prove existence and uniqueness of the solution to the diiraction problem of a plane electromagnetic eld by a chiral curved layer covering a perfectly conducting object. Approximative impedance conditions are given for thin chiral curved layers and optimal error estimates are obtained.

High Order Window Functions and Fast Algorithms for Calculating Dyadic Electromagnetic Green’s Function in Multilayered Media

A type of bell-shaped compact high order window function ψ(x, y) is studied, and closed analytic and approximation formulas are derived for its Hankel transforms. Applications of these results are presented as fast algorithms for calculating dyadic Green’s functions for electromagnetic scattering in multilayered media. Numerical results in electromagnetics are provided to demonstrate the accura...

improving thickness estimation for thin layers in quefrency domain

obtaining a seismic section with high temporal and spatial resolution was always one of the goals of seismic data processors and interpreters. accurate estimation of the thicknesses of thin beds is an important tool in this regard. the basic problem is that the wavelength of the signal must be similar in dimention to that of the bed thinness. if it is much longer than the bed thinness, the dete...
