Evaluation of electrical properties for complex mixtures with a low-frequency periodic technique

This paper presents an efficient numerical technique in evaluating the homogenized anisotropic electrical properties of mixtures with arbitrary inclusions at low-frequency region. The method is based on a low-frequency finite-different method in conjuncture with periodic boundary conditions. Using the developed method, the relationship between micro-scale inclusions and macro-level mixture electrical properties are explored. It is observed that in addition to inclusion volume, inclusion shape and spacing among inclusion objects can also significantly change the homogenized mixture electrical properties.
