Management of rotation center in a two-dimensional nonlinear lattice by injected signal frequency
摘要
Synchronization patterns in two-dimensional nonlinear oscillator lattices influence signal processing and communication systems. This study investigates the behavior of a tunnel diode oscillator lattice under external signal injection, focusing on the control of rotation centers and the extension of the synchronization lock range. Through numerical simulations and experimental validation, we show that rotary voltage patterns dynamically adjust their paths to align with the injected frequency, facilitating synchronization across an extended frequency range through adaptive changes in rotary phase wave trajectories. Experimental results indicate reductions in phase noise levels and demonstrate controlled shifts in rotation center positions, supporting the feasibility of this approach. These findings suggest that the self-organized behavior of internal lattice structures may contribute to the design of frequency-adaptive oscillators for communication and signal processing applications.
