An analysis is presented of k-space coupling of energy from an object into one or more proximal resonant scatterers. The choice of basis function provides insight into coupling mechanisms and efficiency which leads to the design of effective resonant scatterers that can direct energy and/or information associated with high-k evanescent fields away from the object. We discuss the trade-offs between the k-space and ω-space coupling as a function of the Q of the resonant scatterer. At the nanoscale, this has applications for super-Planckian heat removal as well as superresolution imaging.
