A study on the discretization of a distributed RC circuit model

This paper discusses the mixed finite-element based Hamiltonian discretization of a distributed RC circuit aimed at modeling the impedance of rough electrodes of ionic polymer actuators. The accuracy of the discretized model is discussed by comparing the frequency responses between the discretized and the exact solution in the case of the constant impedance distribution. The convergence analysis and the numerical example are shown in order to evaluate the approximation.
