摘要: 在明确介电函数定义及其虚部意义的基础上,比较分析函数ε’(ω)与复介电函数ε(ω)的不同,建议函数ε’(ω)不要称为“复介电函数”或“复电容率”,以免与复介电函数ε(ω)混淆.

Abstract: Based on the ε' (ω) and complex dielectri definition of di function ε (ω) dielectric function. Calling ε'(ω) " complex electric function and the meaning of its imaginary part, the function are compared and analyzed. The function ε'(ω) is not the complex dielectric function.Calling ε'(ω)"complex dielectric function" is not proper.

Key words: dielectric function, conductivity, Maxwell's equations
