kavitetssystem

Kavitetssystem is a term used in science and engineering to describe a system composed of one or more cavities—hollow spaces or resonant enclosures—that interact with energy carriers such as photons, sound, or particles. The concept is used across disciplines to study how confined regions modify the behavior of waves or matter and how these regions are coupled to their surroundings.

A typical kavitetssystem includes the central cavity or cavities, coupling elements that connect the cavities to external channels (such as waveguides, apertures, or mirrors), and the surrounding medium or substrate. The performance of such a system is largely determined by resonance modes, the quality factor (Q) which measures energy retention, and the mode volume which describes spatial confinement. The coupling regime between the cavity and external fields or other cavities—undercoupled, critically coupled, or overcoupled—also strongly influences response and bandwidth.

Common domains of application include:

- Optical and microwave technologies, where optical or microwave cavities confine light or microwaves for lasers, sensors, quantum information devices, and communication components.

- Acoustic engineering, where resonant cavities shape sound propagation in musical instruments, rooms, and speakers.

- Chemistry and biochemistry, where molecular or host–guest cavities in materials (such as zeolites or cyclodextrins) create selective binding sites and influence reactions or separations.

Design and analysis typically involve geometric considerations (shape, size, and arrangement of cavities), material properties, and methods for excitation and measurement. Computational tools (finite element methods, FDTD) and spectroscopic techniques are commonly used to characterize modes, Q factors, and coupling dynamics.
