We have suggested an electrically controlled multifrequency cloak with a single shell of ferroelectric material for the first time to the best of our knowledge. The theoretical and simulated results have demonstrated that this cloak with high-index ferroelectrics can reduce the total scattering cross section of the cloaked system at multiple frequencies. These cloaking frequencies of our cloak can be externally controlled since the dielectric constant of ferroelectrics is well tuned with the applied electric field. It may provide a potential way to design a tunable multifrequency cloak with considerable flexibility.
