Spiral waves on a 2-D array of nonlinear circuits

Spatio-temporal patterns formed in a 2-D array of Chua's circuits have been studied numerically. It has been found that spiral wave solutions can appear over a large range of parameters and some of their properties have been measured. This demonstrates that spiral wave dynamics can be studied in arrays of discrete electronic circuits, such as a 2-D array of Chua's circuits, where real-time results can be obtained. We also study the influence of small differences in the parameters of the circuits, as is the case in real electronic components, where a 5% device tolerance is typical.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
