(a) Three neighboring unit cells of the 6-layer array. It shows all six parallel planar arrays. (The blue transparent cube represents the surrounding concrete material as the host medium). (b) The unit cell of the same array. (c) The unit cell of the infinite periodic planar array of metal helical particles. (d) Nine neighboring unit cells of the array shown in (c). (e) The unit cell of the infinite periodic planar array of metal cylinders (f) Nine neighboring unit cells of the array shown in (e).
