Continuum design sensitivity analysis based force calculation in EM devices

The continuum design sensitivity analysis (CDSA) has been applied to the magnetostatic and electrostatic force calculation. This method allows the computation of the net loading force on a body as well as the force distribution on the surface of the body. An algorithm for force calculation combined with a standard field analysis software package is presented. The efficiency and accuracy of the method is proved through the numerical implementation applied to a set of test examples. In addition, the new approach has several advantages over the traditional methods based on the Maxwell Stress Tensor, such as no air gap or artificial interference with the original model is required. Particularly, the performance analysis of a MEMS micro-mirror using CDSA torque calculation is conducted for the first time.
