A systematic analysis of the interference of four umbrellalike beams (IFUB), including the symmetric IFUB where any two of three ambient beams form the same angle and the nonsymmetrical IFUB where this condition is not satisfied, is provided. It shows that 10 three-dimensional (3D) Bravais lattices out of the total 14 can be produced by means of IFUB. The specific requirements in beam design, the...
A systematic and comprehensive analysis of interference of three equal-intensity umbrellalike beams (ITUB) is provided based on the traditional interference theory. It shows that identical two-dimensional (2D) bright and dark lattices with spacing of the order of wavelength can be fabricated and a partial uniform contrast can be obtained by properly adjusting polarization of each beam. This study...
