ANALYSIS OF THE ELECTROMAGNETIC SCATTERING FROM FLAT PLATES BY USING DIFFERENT SINC-TYPE BASIS FUNCTIONS IN METHOD OF MOMENTS Electromagnetic scattering from three dimensional arbitrary flat surfaces illuminated by a plane wave is investigated by using sinc-type basis functions in the method of moments (MoM) in this study. Task parallel implementation of a solver for electromagnetic scattering problemsI Afshin Zafaria, Elisabeth Larssona,, Marco Righerob, M.

To fully exploit the potential of such systems, it is crucial to analyze the propagation and scattering phenomena of electromagnetic (EM) waves at any frequency, ranging from static and quasi-static regimes to optical wavelengths and even beyond.

All electromagnetic radiation is subject to scattering by the medium (gas, liquid, or solid) through which it passes. In the short-wavelength, high-energy regime in which electromagnetic radiation is most easily discussed by means of a particle description, these processes are termed photon : J. F. Scott. 3. Electromagnetic methods Introduction The electromagnetic techniques have the broadest range of different instrumental systems. They can be classified as either time domain (TEM) of frequency domain (FEM) systems. FEM: use one or more frequencies TEM: Measurements as a function of time.

The invariant amplitude of electromagnetic scattering off a fixed target is thus the integral over the product between the transition current of the projectile and the electromagnetic potential of the target.

Note that this is a local interaction. Current and potential are defined at the same point in space-time. But this point may be anywhere.
