Considering the ion sheath around antenna conductor, the numerical results of the input impedance agreed with the experimental data. The return loss and field distribution were found to be improved by the presence of the ion sheath.ĪB - Wire antenna used for plasma process was analyzed using finite difference time domain (FDTD) method.

The efficiency of the proposed FDTD (2, 4) technique in cold plasma media compared to its conventional FDTD (2, 2) counterpart is demonstrated through numerical results. Meanwhile, it is apparent that numerical error can be reduced when the simulation parameters are selected accurately.T1 - FDTD analysis of wire antenna used for process plasma described and an elaborate study of the stability and dispersion properties of the resulting algorithm is conducted. That is the reason the time step size needs to be below the Courant limit for magnetized plasma FDTD method. Results of numerical experiments to verify the accuracy analysis are presented. Nevertheless, the stability of these formulations is bounded by the Courant-Friedrichs-Lewy (CFL) limit. For completeness, two new FDTD methods for cold plasma, one of which is.
Other numerical approaches for EM wave propagation have also been constructed in the literature. In recent years, the finite difference time domain (FDTD) method, one of the most popular tool in computational electromagnetic, has been successfully used for exploring the unusual electromagnetic properties of the DNG meta-materials 3, 4. In 16, a fourth order FDTD method coupled to a second order leap frog time integrator is used to analyze nonlinear optical materials. This paper proposes a new one-dimensional finite-difference time-domain (1D-FDTD) method to achieve accurate electromagnetic (EM) wave characteristics in plasma region for wideband signals. Numerical results indicate that the stability requirement of the PLCDRC-FDTD scheme for magnetized plasma media is more restrictive than that of FDTD in non-dispersive dielectrics. higher order formulations of the FDTD method have been analyzed for the case of linear media 4,40,41,48,50,52,54. The Stability and the relationships between the numerical dispersion, dissipation errors and different parameters (i.e., EM wave frequency, plasma frequency, and electron gyrofrequency) are studied. The numerical dispersion error and dissipation error caused by the PLCDRC-FDTD method are investigated by comparing the real part and imaginary of numerical wave number with these of analytic wave number. This letter presents a numerical dispersion relation of the piecewise linear current density recursive convolution (PLCDRC) finite-difference time-domain (FDTD) for anisotropic magnetized plasma.
