Gaussian pulse propagation in a linear, lossy chiral medium

Three-Dimensional Gaussian Beam Scattering From a Periodic Sequence of Bi-Isotropic and Material Layers

“…In [25] it has been shown that T 01 T N −1 T = T 01 T N T 13 , and in the block representation (2 × 2) the transfer matrices are (15) where T pv corresponds to the matrices T 01 and T 13 . The blocks of the quasi-diagonal matrices are…”

“…Several beam-wave phenomena such as lateral shift, focal shift, angular shift, beam splitting that are not found in the reflection of plane wave are the major features for investigation. Papers [13][14][15][16][17][18][19][20] are devoted to investigate the wave beam scattering on the structures with the spatial dispersion that include single layers of the natural and artificial reciprocal (chiral) and nonreciprocal bi-isotropic, bi-anisotropic medium, gyrotropic crystals, etc. Most of these studies were based on a two-dimensional beam-wave structure.…”

Electromagnetic Wave Propagation in Dispersive and Complex Material with Time-Domain Techniques

“…The first ideas along these lines seem to be due to Beltrami [2]. In time-harmonic analysis, these fields or generalizations of these fields are referred to as Beltrami fields [22], wave fields [20], self-dual fields [20], or Bohren fields [18]. Wave fields have been used with success in the analysis of monochromatic wave propagation phenomena in linear bi-isotropic materials, see, e.g., Lindell et al [20].…”

Forerunners in bigyrotropic materials

“…The complex field-vector concept is well-known for isotropic and bi-isotropic materials [1,18,29] but seems to be new for general bi-gyrotropic media. The use of complex field vectors simplifies the analysis in Section 3.…”
