The nano-focusing performance of adiabatically designed Cartesian oval refocusing lenses is compared with other well known compound refractive parabolic profiles (both simple concave and kinoform types). Using beam propagation method (BPM) simulation, it shown that our design based on does significantly improve the focusing properties to lens designs, e.g. (AFLs), which doesn't take into account effect. This points importance optimizing complex in improving performance.
