| 摘 要： | 利用二次均质化的近似理论,研究具有组分梯度复合膜的有效介电响应,推导梯度复合膜的有效介电常数。首先,运用Bruggman有效媒质理论,得到梯度膜的z层的等效介电常数。其次,均质化整个梯度膜,求出整个梯度膜的有效介电常数。为突出梯度效应,研究在相同总体积分数的情况下,梯度构型p（z）=a（z/w）m对梯度复合膜的有效介电常数的影响。

| Abstract: | This thesis presents a two-step homogenization method for studying effective dielectric response of compositionally graded films.First,it adopts the effective-medium theory to formulate the equivalent(local) dielectric permittivity tensor for a z slice.Second,the graded composite films are homogenized with an effective(overall) dielectric permittivity tensor including the diagonal and off-diagonal elements.The effective dielectric response is studied as a function with the same total volume fraction.For a p... |
