材料的介电特性可以通过两个参数来描述：介电常数K '和介电损耗因子t0'。有几本书详细介绍了电学和物理推导及其意义（例如，Hill等人，1969和Von Hippel，1954 a）。在极端的概括中，K '是材料储存电能的能力的量度。在微波频率下，当偶极矩能够随着交变电场定向时，K '是大的。K”是从所施加的场吸收的能量的量度。
The dielectric properties of a material can be described by two parameters: the dielectric constant, K’, and the dielectric loss factor, to’. Several texts present a detailed treatment of the electrical and physical derivations and their significance (eg, Hill et al., 1969 and Von Hippel, 1954a). In extreme generalities, K’is a measure of the ability of a material to store electrical energy. At microwave frequencies, K’is large when the dipole moment is able to orient with the alternating electric field. K” is a measure of the energy absorbed from the applied field.
