permittivity
Meaning: A measure of how easily an electric field can form within a given material, indicating the material's ability to store electrical energy in an electric field.
Permittivity is a fundamental property in electromagnetism that determines how a dielectric medium affects the electric field passing through it. It appears routinely in Maxwell's equations and is central to capacitor design, wave propagation analysis, and materials science. The permittivity of free space (vacuum permittivity) serves as a baseline constant against which all other materials are compared.
Examples
- The permittivity of the ceramic substrate made it an ideal choice for high-frequency capacitor applications. 该陶瓷基板的介电常数使其成为高频电容器应用的理想选择。La permitividad del sustrato cerámico lo convirtió en una opción ideal para aplicaciones de condensadores de alta frecuencia.そのセラミック基板の誘電率は、高周波コンデンサ用途にとって理想的な選択肢であった。그 세라믹 기판의 유전율은 고주파 커패시터 용도에 이상적인 선택이었다.
- Researchers measured the permittivity of the new polymer composite to assess its suitability for antenna design. 研究人员测量了新型聚合物复合材料的介电常数,以评估其是否适用于天线设计。Los investigadores midieron la permitividad del nuevo compuesto polimérico para evaluar su idoneidad en el diseño de antenas.研究者たちは新しいポリマー複合材料の誘電率を測定し、アンテナ設計への適性を評価した。연구자들은 새로운 폴리머 복합 재료의 유전율을 측정하여 안테나 설계에 대한 적합성을 평가했다.
- A material's relative permittivity determines how much it can slow the propagation of electromagnetic waves. 材料的相对介电常数决定了它能在多大程度上减缓电磁波的传播速度。La permitividad relativa de un material determina cuánto puede ralentizar la propagación de las ondas electromagnéticas.材料の比誘電率は、電磁波の伝搬速度をどの程度遅くできるかを決定する。재료의 비유전율은 전자기파의 전파 속도를 얼마나 늦출 수 있는지를 결정한다.
