Such arrays can possess high coupling, preventing localized operation of individual transducers. This paper provides insight into how forced vibration localizes in a symmetric system of coupled oscillators. We use a simple lumped-parameter model of highly coupled oscillators derived from ultrasound transducer arrays. Forced vibration localization can be shown to be inversely related to the coupling strength between the oscillators. The results demonstrate how forced vibration in a coupled symmetric system may localize through modal superposition and how it may be tuned via the spacing of natural frequencies. Breaking the system’s symmetry leads to normal mode localization, which can be shown to affect the forced vibration response. The results reveal a variation in the system’s resonance frequency, attributed to curve veering effects.en1424-8220202510Multidisciplinary Digital Publishing Institutehttps://creativecommons.org/licenses/by/4.0/transducer arrays | coupled oscillators | forced vibration | localization | curve veering | modal superpositionNatural Sciences and Mathematics::530: PhysicsTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic EngineeringJournal Article2025-05-27https://doi.org/10.15480/882.1521510.3390/s2510310610.15480/882.15215Journal Article
