Özet

This study presents a statistical method for the focusing point analysis of flat lenses. The proposed method, referred to as the Maximum Beam Intersection method (MBI), analyzes the beam intersection density distribution on the focal axis of a flat lens by means of ray trace analysis. The MBI method not only provides an estimation of the focusing point location but also allows an assessment of the quality of the focusing points. The analysis demonstrates that the ideal imaging effect, obtained in the case of n = -1, has the highest beam intersection density. Results of the MBI method are in agreement with the results of the conventional analytical calculation and the flat lens simulation results.
