Abstract :
We performed a numerical evaluation of the diffraction efficiency of a liquid crystal (LC) grating with binary phase and amplitude distribution profiles based on the Jones calculus of a terahertz wave transmitted through the LC layer. The optimum LC layer thickness for maximum diffraction efficiency was revealed to be much shorter than the LC layer thickness for a π phase difference in the binary phase distribution profile.
