Nonlinear Sensors and Antenna Array
The architecture extends to both 1- and 2-dimensional arrays This approach yields phase gradient values between .+/-.90 regardless of the number of oscillators used.

Researchers at the University of California, Santa Barbara have developed a system that exploits the synchronization properties of coupled, nonlinear oscillators arrays to perform power combining, beam steering, and beam shaping. This architecture utilizes interactions between nonlinear active elements to generate beam patterns. A nonlinear array integrates the signal processing concurrently with the transduction of the signal. This architecture differs fundamentally from passive transducer arrays in three ways: 1) the unit cells are nonlinear, 2) the array purposely couples the unit cells together, and 3) the signal processing (beam steering and shaping) is done via dynamic interactions between unit cells.

Background Passive sensor or radiative arrays have traditionally employed linear, independently controlled transducers (also known as "radiators") as the constituent elements of the array. The geometry of these elements controls the radiation of the beam pattern and signal processing gain. The maximum gain possible is proportional to the number of antenna elements. Reciprocity permits the process to be reversed for the transmission of signals. Solutions to phase-shifterless beam steering have been investigated but the scanning ability of alternative methods was very limited.
