Scattering efficiency spectra, Q sca, for a uniform-graphene coated cylinder illuminated by a TEz-polarized plane wave, when the radius R varies, maintaining fixed ε d = 3.9 and μ = 0.5 eV. We included analytical equations (7) and (8) indicating the resonance condition and the invisibility condition, respectively.
