“…However, the magnetoelectric coupling that characterizes the bi-isotropic media makes the extension of the FDTD method to incorporate bi-isotropic media a challenging problem. First attempts can be found in [39][40][41]. In these works extensions of Berenger's PML for bi-isotropic and bi-anisotropic media are developed assuming that the constitutive parameters are constant with frequency.…”

The finite-difference time-domain (FDTD) technique for simulating electromagnetic wave interaction with a dispersive chiral medium is extended to include the simulation of dispersive bianisotropic media. Due to anisotropy and frequency dispersion of such media, the constitutive parameters are represented by frequency-dependent tensors. The FDTD is formulated using the Z-transform method, a conventional approach for applying FDTD in frequency-dispersive media. Omega medium is considered as an example of bianisotropic media, the frequency-dependent tensors of which are based on analytical models. The extended FDTD method is used to determine the reflection and transmission coefficients of co-and cross-polarized electromagnetic waves from omega slabs, illuminated by normally incident plane waves. Three cases are simulated: 1) a slab of uniaxial omega medium with its optical axis parallel to the propagation vector; 2) a slab of rotated uniaxial omega medium with its optical axis not parallel to the propagation vector; and 3) a slab of biaxial omega medium. The results are validated by means of comparisons with analytical solutions.Index Terms-Bianisotropic media, chiral medium, dispersive media, finite-difference time-domain (FDTD), omega medium, Z-transform method.

“…The time-domain schemes that have been utilized to model chiral or bi-isotropic (BI) media to date are overly complex and none have been successfully generalized to include the dispersive behavior of these materials. One successful attempt at modeling BA media using finite-difference time-domain (FDTD) was reported by Garcia et al [22]. The authors extend Berenger's perfectly matched layer (PML) concept to include BA media, where a monochromatic plane wave propagating in a two-dimensional (2-D) chiral medium is modeled as a test case.…”

This paper presents an extension of the recently developed finite-difference time-domain (FDTD) technique for modeling electromagnetic wave interactions with bianisotropic (BI) media, known as BI-FDTD, to include the more general class of bianisotropic materials. This new FDTD formulation is called BA-FDTD. The theoretical foundation for this method is based on a wavefield decomposition technique. The formulations based on the application of this wavefield decomposition technique to BA media will be presented. Validations of this new model are demonstrated for the interaction of an electromagnetic wave propagating transversely through a uniaxial BA half-space. Index Terms-Bianisotropic (BA) media, chiral media, finite-difference time-domain (FDTD) methods.
