Abstract
This contribution investigates a photosensitive circuit based on a mutator for emulating memristor, memcapacitor, and meminductor. The circuit contains a phototube, a mutator, and several basic electronic components. The phototube is employed within the circuit to capture the external illumination for energy injection in order to obtain a continuous signal source. By varying the light intensity on the phototube, chaotic dynamics such as attractors, bifurcation diagrams, and Lyapunov exponents spectrum are analyzed, while the mutator is switched to different mem-elements without changing the structure of the circuit. Especially, the special phenomenon of the coexistence of attractors is discovered. Ultimately, the circuit is realized using DSP. This circuit holds promise in offering potential insights into the dynamics of neural networks, and it could find applications in the development of highly sensitive sensors.
期刊介绍：
The International Journal of Bifurcation and Chaos is widely regarded as a leading journal in the exciting fields of chaos theory and nonlinear science. Represented by an international editorial board comprising top researchers from a wide variety of disciplines, it is setting high standards in scientific and production quality. The journal has been reputedly acclaimed by the scientific community around the world, and has featured many important papers by leading researchers from various areas of applied sciences and engineering.
The discipline of chaos theory has created a universal paradigm, a scientific parlance, and a mathematical tool for grappling with complex dynamical phenomena. In every field of applied sciences (astronomy, atmospheric sciences, biology, chemistry, economics, geophysics, life and medical sciences, physics, social sciences, ecology, etc.) and engineering (aerospace, chemical, electronic, civil, computer, information, mechanical, software, telecommunication, etc.), the local and global manifestations of chaos and bifurcation have burst forth in an unprecedented universality, linking scientists heretofore unfamiliar with one another''s fields, and offering an opportunity to reshape our grasp of reality.
