| Abstract: | Nonlinear composite dielectrics prepared by polymer added nonlinear filler was chosen as the research object,filler particle random distribution in matrix and models random construction based on Montecarlo simulation was realized by programming,and response currents under different voltage excitation were obtained by 3D FEM software.Then time-domain least square method was adopted to decompose the total current from simulation,then the macro dielectric parameters of material are obtained.The results show th... |
