Efficient modeling of isotropic cold plasma media using JE-TLM method

Abstract

New simulation technique, by the transmission line matrix method (TLM), of electromagnetic waves in dispersive cold plasma media is proposed. This technique exploits the dependence of the current density J and the electric field E, and the derivation of the ordinary differential equations (ODE) by the exponential fitting method. The TLM Model uses the standard symmetrical condensed node (SCN) with 12 principal ports and 3 additional ports in which we incorporate voltage sources to model the dispersive behavior of cold plasma media. To investigate the accuracy of this approach, reflection and transmission coefficients of non-magnetized plasma wall are computed. Also the farzone scattering results of a cold plasma sphere are presented. All the obtained results, using the new modeling technique named JE-TLM are in good agreement with those of the theoretical ones.

New Scattering Matrix Model for Modeling Ferrite Media Using the TLM Method

“…To find the scattering matrix of the new HSCN modeling magnetized ferrite, three supplementary stubs (16,17,18) are added to the standard (15×15) HSCN. In these stubs, equivalent current sources (I sx , I sy , I sz ) are respectively included to model the gyromagnetic properties of the ferrite [17].…”

“…In light of this, numerical methods are a strong and inevitable alternative to deal with these problems. The transmission line matrix (TLM) method [7] is one among many time-domain numerical techniques that have been successfully used to study the interaction of EM waves with isotropic and anisotropic media [8]- [16]. Using different additional techniques to include frequency-dependent material properties in the time domain, this method is able to model several dispersive media.…”

“…The third approach has been developed using the insertion of an equivalent circuit [1]. The last one models the dispersive media by adding voltage [11]- [16] and/or current sources [17], [18] in the TLM nodes.…”

Modeling of Optical Pulse Propagation in Kerr and Raman Nonlinear Dispersive Media Using Je-TLM Method

“…One of these algorithms that have been incorporated with the TLM method is the Z-transform technique [12], and another is CRC-TLM recursive convolution (CRC) combined to voltage and current sources [13] and the Auxiliary Differential Equation ADE-TLM [14]. However in our case, we use the JE-TLM that exploits the current density and the electric field that has been used to model isotropic cold plasma [15,16] and used to simulate the propagation of optical pulses in two-level atomic systems [17]. In this paper, we increase a novel algorithm based on the JE-TLM method with condensed symmetrical node (SCN) and new voltage sources.…”

Modeling of anisotropic magnetized plasma media using PLCDRC-TLM method

“…In the third approach, shunt and series transmission lines with one-port equivalent circuits are used to model the permittivity and the permeability of the media [10]. The fourth one consists of the use of voltage and/or current sources to describe the dispersive behavior [11][12][13][14][15]. The last approach was recently used with the constant recursive convolution (CRC) technique to model ferrite media [16] the RKETD [17] and current density recursive convolution (CDRC) to model anisotropic magnetized plasma [18].…”
