Interaction of electromagnetic waves with general bianisotropic slabs

Efficient analysis of multi-resonant periodic structures for the improved analysis and design of reflectarray antennas

“…3(a) we show the results obtained for the phase of S xx (patches of Fig. 1 located in a two-layered substrate) with the purely numerical MoM-SD approach and with the closedform rational fitting expression of (8) in the case where N = 2 and M = 3 (rational function with two zeros and three poles). Note that there is a good agreement between the two sets of results, and that the relative error is on average around 0.1%.…”

“…The scattering matrix S XY can be written as S XY = S X Y + S XY , where -wd S XY accounts for the effect of the multilayered substrate in the absence of the patches, and a scattering matrix S y 7 which -wd accounts for the effect of the patches. The matrix S XY can be easily computed in terms of 4 x 4 transition matrices as shown elsewhere [8]. The computation of the matrix S XY demands a larger CPU time, and can be carried out by means of the method of moments in the spectral domain (MoM-SD) [4] based on multilayered Green's function (MGF) [5].…”

The Combined Effects of Chiral Operation in Multilayered Bianisotropic Substrates

“…Furthermore, the general solution to the vector differential Eq. (7) can be found: Under the excitation of a dipole antenna on the multilayered bianisotropic chiral substrate, the far field distributions in the air region (z > 0) can be derived using the saddle-point method, i.e., [3] …”

“…It is known that the exponential matrix technique in spectral domain has often been utilized for investigating the interaction of electromagnetic waves with bi(an)isotropic media [3]. To some degree speaking, such a technique is efficient and powerful to deal with most linear complex materials, and it has been employed in the author's previous study and improved more recently [14,28].…”

“…Bianisotropic linear materials are characterized by four independent constitutive tensors, and till now significant theoretical research progress has been achieved concerning the electromagnetic characteristics and potential applications of some bianisotropic materials. For instance, the dyadic Green's function theory for source radiation and wave propagation in uniaxial and helicoidal bianisotropic media [2][3][4][5][6][7][8], wave reflection and transmission properties of multilayered bianisotropic slabs and their potential applications for making novel non-reflection coatings and filters [9][10][11][12][13][14][15], the guided hybrid mode features in some bianisotropic waveguides [16][17][18][19][20][21][22][23][24], the dispersion characteristics of bianisotropic microstrip transmission lines and the effects of bianisotropic substrate and su-perstrate on the radiation of sources [25][26][27][28], the scattering from some particular bianisotropic objects [29][30][31], the edge effect in bianisotropic region [32,33], and the macroscopic properties of bianisotropic mixtures as well as experimental investigations on the effective constitutive parameters of uniaxial bianisotropic composites [34][35][36][37][38][39], et al In these studies the authors usually pay attention to the diverse chiral effects in bianisotropic med...…”
