Dn. Chigrin et Av. Lavrinenko, GENERALIZATION OF THE EFFECTIVE-MEDIUM METHOD FOR CONTINUOUSLY INHOMOGENEOUS-MEDIA, Electromagnetics, 17(3), 1997, pp. 287-294
Subsequent development of the effective medium method is considered. T
he effective material parameters are introduced in the coordinate-free
form for continuously inhomogeneous stratified reciprocal bi-isotropi
c and anisotropic media.
