The permittivity of an insulating ordielectric materialis symbolized as ε. In electrical engineering applications, permittivity is often expressed in relative rather than absolute terms. Simply put, relative permittivity is the ratio of the permittivity of a substance or material to the permittivity of...
在英语中表征“介电常量/数”这个物理量的名词有3 个:dielectric constant 或者dielectric function 或者permittivity。这样,其中文直译依次为:介电常数,介电函数,电容率。然而,由于历史原因,在现行的中文教科书和科技文献中几乎都采用dielectric constant 的翻译“介电常数”来...
A novel method for measuring the complex permittivity of dielectric plates is proposed by using TM0mn modes in a closed cylindrical resonant cavity.The analysis based on the Ritz-Galerkin method,mode matching technique and transmission-mode quality factor measurement method is performed,and the formula...

and measured values of permittivities of low-loss polyvinyl-chloride and polytetrafluoro.ethylene samples (less than 8 percent for dielectric constant and less than 15 percent for loss tangent values). 1. INTRODUCTION Material characterization is an important issue in many material production, proc...
The meaning of PERMITTIVITY is the ability of a material to store electrical potential energy under the influence of an electric field measured by the ratio of the capacitance of a capacitor with the material as dielectric to its capacitance with vacuum
The paper gives the results of room-temperature measurements on ceramic (polycrystalline) specimens of magnesium, calcium, strontium and barium titanates at frequencies of 1.5 and 9450 Mc/s (3.18 cm), and on barium titanate at 24000 Mc/s (1.25 cm). It is found that the latter material is...
