Cr. Simovski, FIRST-ORDER SPATIAL-DISPERSION AND MAXWELL-GARNETT-MODELING OF BIANISOTROPIC MEDIA, AEU-INTERNATIONAL JOURNAL OF ELECTRONICS AND COMMUNICATIONS, 52(2), 1998, pp. 76-80
A recently-developed theory determines the material parameters of bian
isotropic composite media formed By inclusions embedded into the diele
ctric matrix by application of the Maxwell Garnett approach when the r
esponse of the individual inclusion upon the external (local) field is
assumed to be known. In this theory, the electromagnetic dipole model
of the inclusions mast be considers, Such a model can be non-invarian
t with respect to the choice of coordinate origin in Ease of bianisotr
opic inclusions that have both induced magnetodipole and electroquadru
pole moments. In this paper we discuss the constitutive relations obta
ined in the framework of first-order spatial dispersion approximation,
and se express material parameters by those of an individual particle
, taking into account the induced quadrupoles. The Maxwell Garnett for
malism approach is applied.
