Cavity Resonators

A cavity resonator is a specialized metal container designed to store and sustain electromagnetic energy at specific frequencies. By shaping and sizing the cavity accurately, it enhances certain radio or microwave signals, acting like a musical instrument that resonates at particular notes. These devices are commonly used in communication systems, radar, and scientific experiments to filter, generate, or measure high-frequency signals with high precision. Their effectiveness depends on their geometry and material, which help confine and amplify electromagnetic waves within the cavity.
