Abstract:
Two-dimensionalmagnetostatic cloaks, evenwhen perfectly designed tomitigate the magnetic field disturbance
of a scatterer, may be still detectable with Aharonov-Bohm (AB) measurements, and therefore may affect
quantum interactions and experiments with elongated objects. We explore a multilayered cylindrical cloak
whose permeability profile is tailored to nullify the magnetic-flux perturbation of the system, neutralizing its
effect on AB measurements, and simultaneously optimally suppress the overall scattering. In this way, our
improved magnetostatic cloak combines substantial mitigation of the magnetostatic scattering response with zero
detectability by AB experiments
