Mirror Combination Scheme in Reciprocal Lattice

In the last chapter, we studied about the construction of Wigner–Seitz cells in 1-D, 2-D and 3-D lattices and the related aspects. The Wigner–Seitz cells are found to possess certain sets of equivalent parallel mirrors (and hence work in accordance with mirror combination scheme) which are capable of producing infinitely extended 1-D, 2-D and 3-D lattices, where each of them exhibits perfect translational periodicity.
