%X We present an accurate and efficient algorithm to calculate the electrostatic interaction of charged point particles with partially periodic boundary conditions that are confined along the nonperiodic direction by two metallic parallel plates. The method preserves the original boundary conditions and hence, it does not introduce any kind of artifacts. In addition, it enjoys the quasilinear complexity of $\mathcal{O}(N\ln(N))$, where $N$ being the number of particles in the simulation box. In fact, based on the superposition principle in electrostatics, the problem is split into two electrostatic problems where each one can be calculated by the appropriate Poisson solver. In this paper we apply the method to sodium chloride ultrathin films and investigate its dielectric response with respect to external bias voltage. We show how accurately in this method one can obtain the total charge induced on metallic boundaries to an arbitrary precision.
