Abstract :
In this paper, an efficient approach is used to evaluate the stochastic variations of the bulk permittivity for complex periodic composite material. This method is based on the stochastic collation method together with a periodic 3-D finite-difference approach. Based on the proposed method, the influence of the input uncertainties (e.g., mixture inclusion permittivity, conductivity, volume fraction, and host cell periodicity) on the complex bulk permittivity is discussed.
