Localized mode in one-dimensional anharmonic electronic circuit system

Harmonic approximation is an approximation method often used in physics research, but in actual experimental research, the results obtained are not completely consistent with the phenomena obtained using the harmonic approximation, which is due to the influence of anharmonic effects on the research object. In this paper, the variation of localization phenomena under the influence of anharmonic effects is investigated based on a numerical simulation model of electronic circuit system design. The localization modal images generated at the boundary of the Brillouin zone are obtained in a one-dimensional anharmonic lattice constructed by the electronic circuit. The numerical simulation results can reflect the location of the region boundaries in the electronic circuit system model. The simulation results show that the intrinsic localized mode is affected by the change of frequency.
