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

Abstract

This paper aims to extend the transmission line matrix method with a hybrid symmetrical condensed node (HSCN) to model ferrite media in the time domain. To take into account the anisotropy and dispersive properties of ferrite media, equivalent current sources are incorporated into supplementary stubs of the original HSCN. The scattering matrix of the proposed HSCN is provided, and the validity of this approach is demonstrated for both transversely and longitudinally magnetized ferrites. Agreement is achieved between the results of this approach and those of the theoretical and the finite‐difference time‐domain method.

Modeling of anisotropic magnetized plasma media using PLCDRC-TLM method

“…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].…”
