Abstract

New solutions to the problem of focusing the beam of round cross section into the rectangle are analyzed by the computer simulation. It has been found that the theoretical power efficiency of focusators is 82-85% for the case of focusing into the rectangle with the sides which are 10- to 100-fold longer than the diffraction spot size.
