Webcorresponds to the depth of a 1D lattice created by two counterpropagating beams, where I 0 is the light shift produced by one of the lattice beams. The corresponding reciprocal lattice vectors b i can simply be derived through the relation b i = ijk(k j −k k), while the primitive direct lattice vectors follow according to a i ·b j =2πδ i,j. WebDate Issued. 2011. Description. Lattice materials possess a spatially repeating porous microstructure or unit cell. Their usefulness lies in their multi-functionality in terms of …
