Abstract

We investigate the focusing performance of a closed-boundary axilens with long common focal depth by boundary integral euquations. The common extended focal depth of a cylindrical micro-axilens, illuminated by different incident wavelengths is numerically simulated, and the electric field intensity distribution is numerically determined by the boundary element method. The results show that the long common focal depth is changed when the preset focal depth is increased.
