Investigation of The Electromagnetic Force Effect in N/MEMS Switch by HomotopyPerturbation Method

The effect of the electromagnetic force parameter and the relation between wire displacements are vitalconsiderations in the design of nano/microelectromechanical systems. In this paper, a semi -analyticalmethod called the Homotopy Perturbation Method (HPM) has been applied to solve nonlinear equationsof a nano/microelectromechanical systems switch. The results for various values of electromagneticforce are shown to demonstrate the method's validity. Additionally, it was determined that the providedmethod is exact and effective for the given situation. The results in all situations prove the accuracy ofHPM, where all of the calculations have a striking similarity to the numerical approach. This approachis beneficial for the solution of a large number of nonlinear equations.
