Abstract
Abstract Synaptic antennas or other radio frequency interactive systems variable in response to photon energy stimuli, are provided from a three-dimensional matrix of electrically conductive segments with photoresponsive devices selectively separating numerous adjacent segments from each other and alternatively interconnecting segments with each other in response to photon energy stimuli. Photon energy stimuli supplied to a first array of photoresponsive devices provide a first combination of interconnected segments constituting a first radio frequency interactive configuration in the matrix. Conversely, photon energy stimuli supplied to a second array of the photoresponsive devices provide a second combination of interconnected segments constituting a second radio frequency interactive configuration in the matrix. A third radio frequency interactive configuration in the matrix different from the first and second radio frequency interactive configurations may be provided by supplying photon energy stimuli to a third array of the photoresponsive devices, different from the first and second arrays, to provide a third combination of interconnected segments, and so forth.
