1. An agile holographic phased array for electromagnetic radiation comprising:

  • a first diffractive structure that diffracts electromagnetic radiation into one or more fundamental diffractive orders,a spatial and temporal modulator with the capability of adjusting the phase shift undergone by electromagnetic radiation diffracted from the diffractive structure in a predetermined spatial and temporal pattern, and the spatial and temporal pattern having a spatial resolution finer than 1000 wavelengths of the electromagnetic radiation and a temporal resolution finer than 1 second, such that the spatial and temporal modulator can generate diffraction suborders from the one or more fundamental diffracted orders.
