Electromagnetic homogenization of particulate composite materials comprising spheroids and truncated spheroids with orientational distribution
Héctor M. Iga-Buitrón, Tom G. Mackay, Akhlesh Lakhtakia
Implementations of the Bruggeman and Maxwell Garnett homogenization formalisms were developed to estimate the relative permittivity dyadic of a homogenized composite material (HCM)…
