The paper proposes the use of a nondestructive electromagnetic (NDE) method for evaluation zirconia coating on AISI 316L, based an (EM) sensor with metamaterial lens.Metamaterials (MM), namely conical Swiss roll (CSR), operated in radiofrequency range can serve as EM flux concentrators.EM lens composing sensors are designed basis Fourier optic principles and allows enhancement spatial resolution order to evaluate quality surface /adhesion coating-support.Complementary methods such scanning electron microscopy (SEM), X ray diffraction (XRD) neutron (ND) employed studies samples taken into consideration.
