In the original published paper,1 eq 3 should be corrected to ϵ'μ″ + μ'ϵ″ ≈ Nϵ0μ0(αe″ + αm″) < 0 (1) In this Addition/Correction, we point out that the antiresonance in dielectric resonators can help achieve the negative-index condition, eq 1. Antiresonance in resonant dielectric particles is the anomalous magnetic response at the electric resonance (or vice versa).2,3 The imaginary part of the polarizabilities αe″ and αm″ can be negative at the antiresonance, and thus, eq 1 can be satisfied by using resonant dielectric particles. This is also consistent with the discussion on the antiresonance in page 1373 of the original manuscript.1.
