(a) The different layers of the 6-layer array. (b) The possible path for even layers that are made of pure concrete without conductive particles. (c) The possible sub-paths for each planar array of helical particles. (d) This circuit model represents each path that the power travels through from one side of the slab to the other. A 2-port corresponds to each possible path of the unit cell of the 6-layer array, specified by its scattering matrix [S]. There are 66 distinct paths among which the total incident power is distributed.
