A method is described which elucidates propagation of an electromagnetic field generated by a stochastic, electromagnetic source within the short wavelength limit. The results can be used to determine statistical properties of fields using ray tracing methods.

Electromagnetic radiation is energy that interacts with matter. The interaction process is of great importance to the sensing applications that characterize material media. Parameters like constant dielectric represent matter characteristics and they are identified using emission, interaction and reception of electromagnetic radiation in adapted environmental conditions. How the electromagnetic...

The operating principle of electromagnetic rail gun by store capacitor was analyzed. A simulation model about the bullet velocity in the electromagnetic rail gun was built. The results of computer simulation experiment showed the relationships between the bullet velocity and the capacitor charging voltage and the pellet mass. By ten coil targets, a new kind of measuring method for the bullet ve...

A numerical method for transient electromagnetic scattering by uniformly moving target is proposed. Two reference systems are adopted: one is attached on the radar platform while the other is fixed on the target. Finite Difference Time Domain (FDTD) method is employed to analyze the scattering in the target system. Lorentz transform is exploited to transfer the electromagnetic fields between th...

Although full wave electromagnetic systems are large and cumbersome to solve, typically only a few parameters, such as inpul impedance, S parameters, and far field pattern, are needed by' the designer or analyst. A reduced order modeling of these parameters is therefore an imt)ortant consideration in minimizing the CPU requirements. The Asymptotic Waveform Evaluation(AWE) method is one approach...

One of the interesting Laser-Plasma phenomena, when the laser power is high and ultra intense, is the generation of large amplitude plasma waves (Wakefield) and electron acceleration. An intense electromagnetic laser pulse can create plasma oscillations through the action of the nonlinear pondermotive force. electrons trapped in the wake can be accelerated to high energies, more than 1 TW. Of t...
