a, b Real part and imaginary part of complex permeability of EG, CEG-2, CEG-4 and CEG-6. c, d Real part and imaginary part of complex permittivity of EG, CEG-2, CEG-4 and CEG-6. e Dielectric loss tangent (\(\tan {\delta }_{\varepsilon }\)) of EG, CEG-2, CEG-4 and CEG-6. f \({\varepsilon }_{p}^{{{\hbox{'}}}{{\hbox{'}}}}\) of CEG-2, CEG-4 and CEG-6. g, g1 The charge density difference of heterointerface of CuCo2S4@EG. h, h1 The charge density difference of defect CuCo2S4. i, i1 The charge density difference of nonperfect EG. Blue-green color represents charge depletion, while yellow color represents charge accumulation.
