该算法将配电网中的功率量测变换为电流量测，实现了雅可比矩阵常数化，支路电流实虚部解耦求解。
Power measurements are all transformed to equivalent current measurements that make the Jacobian matrix constant and calculates current real and imaginary part dividualiy.
介电常数虚部大（绝对值），而且包层模序也大时，损耗较大。
The loss is greater when the imaginary part of the complex dielectric constant is bigger and the mode order is higher.
微分散射截面的变化主要依赖于相对介电常数实部、虚部数值较大的一方，并且随粒子取向角的增大而增大。
The variation of DSCS depends on the larger part between real part and imaginary part of dielectric coefficient. The DSCS and azimuth angle are in proportional relation.
如果介电常数的虚部不等于零，则存在能量损失(不管实部为多少)，因而，可以认为该元件具备电阻性。
Finally, if the imaginary part of the permittivity is not equal to zero and so energy is lost (whatever the real part is), then the element can be thought of as having resistance.
另外，当通过复介电常数的虚部引入光学增益后，我们发现缺陷模在增益介质中被放大，其阈值特性和缺陷折射率的密切相关。
We find that dispersive properties inside the micro-cavity lead to frequency shift of the defect modes. The defect modes can be amplified as optical gain is introduced into system.
