Abstract
Parametric coupling device for traveling-waves, comprising a first signal wave, a second idler wave and a third pump wave, wherein a transmission line for said traveling-waves is formed on a substrate of dielectric material, which comprises a virtually continuous network of non-linear interaction elements, modulated by the pump wave, and so modulating the conduction properties of the transmission line and enabling intermodulation to be set up between the various traveling-waves. The virtually continuous network of non-linear interaction elements is a substantially plane network, each non-linear interaction element being at a distance a, or pitch of the network, from a neighbouring non-linear element, the distance a being less than the smallest of the wavelength of the signal, idler and pump waves and the plane network being disposed in the neighborhood of the upper surface of the transmission line.
