Implementation of complete two-dimensional bandgap in photonic crystals of square Bravais lattice using complex unit cell;

In the past, Niggli's cell could be used to obtain indirectly the type of Bragg's lattice to which the unknown crystal lattice belongs by crystal lattice pattern, but this new method is different from Niggli's, in that, it can directly and conveniently get the same result, and also a new term, coordination shape, is coined in this article.

Modal characteristics and leakage loss of hollow-core photonic bandgap fibers based on a square lattice;

The critical temperature of the paramagnetic-ferromagnetic phase transition on the Ising model of the square lattice is studied by means of the Monte Carlo method.

The evolution dynamics of 2_D square lattice probability cellular automata is mapped onto a special 3_D Ising Spin Body_Central _Cubic Lattice model.
