Some microobjects can concentrate an incoming incident plane wave and produce the so- called photonic nanojets. The highly focused emerging beams have a high intensity and can be used in applications in microscopy, beam manipulation and imaging. In this article, it is shown that an adequate choice of geometric shape and material can lead to an improvement of the electric field enhancement capacity of nanojets by a factor of 40%.
