Two Dimensional Models

The following two dimensional models were developed to gain a better understanding of the kind of microstructural features that can give rise to a dielectric amplification mechanism, with and without a percolated highly conductive phase. Although two-dimensional, these models were formulated to capture the essential physics of 3-D microstructural features that can result in dielectric amplification. Both models are formed from 20x20 pixel digital images and consist of two phases, pore solution and C-S-H. The phases have the same properties as given in Table 1, except that εC-S-H = 1000 instead of 500, for the sake of simplicity. The absolute value of the effective dielectric constant is not of great importance in these models, but, rather, the amount of amplification that may be produced based on the geometry of the microstructure.
