Abstract :
Theory asserts that three-dimensional arrays of electrically small particles are excellent media for wave-mixing processes at microwave and millimeter wavelengths. As a specific example, spheres that are free to move on a stack of flat, transparent surfaces and that interact with incident radiation are examined. Electrostrictive forces move the spheres in such a way as to form density index gratings that can be used for controlling the propagation characteristics of coherent radiation. Phase conjugation in this medium is also examined.<>
