Resonator

A resonator is a device or system that exhibits resonance, storing and oscillating energy at specific frequencies called natural or resonant frequencies.

Resonator

A resonator is a fundamental physical system that can store and oscillate energy between different forms, typically exhibiting maximum amplitude at specific frequency frequencies. These systems play crucial roles across multiple domains of science and technology.

Physical Principles

The core behavior of resonators emerges from the physics of oscillation. When a resonator receives energy at its natural frequency, it experiences resonance, leading to:

  • Amplified oscillations
  • Energy storage between different forms (e.g., kinetic and potential)
  • Characteristic frequency response patterns
  • damping effects that gradually dissipate energy
