Information Transmission Concept Based Model of Wave Propagation in Discrete Excitable Media

A new information transmission concept based model of excit able media with continuous outputs of the model’s cells and varia ble excitation time is proposed. Continuous character of the outputs insti gates infinitesimal inaccuracies in calculations. It generates countless numb er of the cells’ excitation variants that occur in front of the wave even in the h omogenous and isotropic grid. New approach allows obtain many wave propag ation patterns observed in real world experiments and known simulation stu dies. The model suggests a new spiral breakup mechanism based on tensions an d gradually deepening clefts that appear in front of the wave caused by un even propagation speed of curved and planar segments of the wave. The analysis hints that the wave breakdown and daughter wavelet bursting behavior poss ibly i inherent peculiarity of excitable media with weak ties between the ce lls, short refractory period and granular structure. The model suggested is locat ed between cellular automaton with discrete outputs and differential equation based models and gives a new tool to simulate wave propagation patterns in app lied disciplines. It is also a new line of attack aimed to understand wave bursting , propagation and annihilation processes in isotropic homogenous media.
