Abstract
A comprehensive study of the time-harmonic, infinite medium dyadic Green function (of the electric type) for the most general uniaxial bianisotropic medium is presented. Such a medium is characterized by eight independent real or complex parameters. The general solution for the dyadic Green function for the radiation problem is obtained and, where possible, closed-form results are presented. Materials displaying the characteristics of uniaxial bianisotropy can be obtained by forming composites of electrically small inclusions with uniaxial scattering responses embedded in an isotropic dielectric/magnetic host medium. Therefore uniaxial bianisotropic media have considerable potential in the fabrication of optical and electronic devices. The general results obtained are applied to a number of special cases which, as manifestations of particulate composites, have attracted much recent interest.Keywords
