noun
- A pattern of motion or vibration in a physical system that oscillates at a single natural frequency without changing shape.
Usage: technical; physics and engineering
Examples
- The first eigenmode of a vibrating string corresponds to its fundamental frequency.
- Engineers analyze the eigenmodes of a bridge to predict how it will respond to wind and traffic.
- Each eigenmode of the system has a characteristic frequency and shape.
- The eigenmode decomposition helps simplify the analysis of complex mechanical systems.
- Acoustic eigenmodes in a concert hall determine which frequencies resonate most strongly.
