A review of the nonimaging concentrator method of design called Poisson brackets method is presented. The method is valuable for 2D and 3D concentrators. The 2D version of the method has provided an interesting concentrator: the CTC (Compound Triangular Concentrator). Unfortunately, so far only impractical 3D concentrators (with variable index of refraction) have been obtained with the 3D version of the method. Nevertheless, these 3D concentrators prove that there are optimal and ideal 3D concentrators besides the trumpet concentrator and the trivial cases.
