| Abstract: | Multi-wavelength fringing electric field sensors have been widely used in industry process control for property measurement of the multilayer material. The key point of parameter estimation algorithm lies in how the relationship between the sensor output and multilayer properties is constructed. The paper focuses on the three-wavelength interdigital sensor. The nonlinear regression model is constructed based on the 3D finite element simulation, which describe the relationship between the multilayer material dielectric property. The experiments of parameter estimation are done, the results show that the algorithm is effective. |
