It has been proposed in the literature that a uniaxial bianisotropic chiral medium can be manufactured by aligning helices in a host material such that their axes are parallel to each other. In this paper, such a uniaxial bianisotropic material is fully characterized for the first time in a purely numerical environment and its effective constitutive parameters are obtained via a combination of numerical and analytical techniques. This new materials characterization methodology completely accounts for all self- and mutual-coupling between the particles. Data confirming the accuracy of this methodology is presented for rod-shaped particles and arrays of helices at oblique angles of illumination. During the course of this work, it was found that certain restrictions must be imposed on the dimensions of the helical inclusions so that they scatter as uniaxial objects.
