| Abstract | Show full text abstract about I will speak about newly emerging approaches for designing w...» I will speak about newly emerging approaches for designing wave fronts that are optimal for various purposes such as for focusing waves on a target, for manipulating small particles with light, or for precision measurements in general. The theoretical concept enabling the optimal solutions for all of these diverse applications turns out to be an operator introduced by Wigner and Smith based on a system’s scattering matrix. I will provide a review of this concept and shall illustrate how experimental access to the Wigner-Smith operator enables wave-front shaping protocols at the optimal level of efficiency.
