Abstract
Abstract A multimode oscillator is disclosed, comprising an array of interconnected oscillator elements distributed over at least two dimensions. The oscillator elements include a grid or network of impedance elements. Three or more inductive (capacitive) elements may radiate from each junction point in the grid, and a capacitive (inductive) element may be shunted to ground from each junction point. Other arrangements of impedance elements are also possible. For pattern recognition, the oscillator elements may also include radiation sensitive elements for selectively controlling the activation of the oscillator elements. Thus, the incident pattern of light, infrared, ultraviolet, X-ray, sound or other radiation controls the number and selection of the simultaneous modes of oscillation in the multimode oscillator. The radiation sensitive elements may be shunted across the capacitive, inductive or other impedance elements and may take the form of radiation sensitive transistors, diodes, resistors, thermistors, switches, microphones or other devices. The multimode oscillator may be either passive or active. Sustained oscillations may be produced in a passive multimode oscillator by providing feedback means between the output and input of the oscillator. An active multimode oscillator employs active elements capable of sustaining the oscillations in the oscillator. Such active elements may include various negative resistance elements such as tunnel diodes. For pattern recognition, active elements may be employed which are also radiation sensitive. Alternatively, the multimode oscillator elements may include both active elements and radiation sensitive elements arranged to control the activation of the active elements. The multimode oscillator may utilize superconductive elements which may be arranged to form a superconductive grid or network to provide an array of inductive elements. The capacitive elements may be provided by the distributed capacitance between the superconductive grid and a superconductive ground plate or surface.
