- Abstract
- In this paper, some simulation results are provided that show the effectiveness of using MFG technique for transferring an input field distribution to any desired multi-locations. In general, the CFT (Cascaded Fresnel Transform) [1] [2] plays the role of imaging an input field distribution to a corresponding location at the output plane via a lens as shown in Figure 1 where the output distribution is magnified aoocrding to determined by the ratio of h / L. However, the proposed MFG technique not only does the role of the CFT but reproduces the input distribution to the desired multi-locations simultaneously as in Figure 2. Applyting MFG technique is composed of two main components: MFG grating and a lens. The MFG grating peforms multi-directional phase shifting on incoming field distribution so that the incoming field goes out into multi-directions simultaneously. The F2 lens plays the role of imaging. So the behaviour of the proposed technique can be explained by the combination of the MFG grating and the 2F lens. In this paper, we presents some experimental results that show the results of applying the proposed MFG technique to an input field distribution and the resuliting output field distribution which shows the overall transferring work flow from the input one to the multi-located ones.
