responsible for antiresonant behavior of the effective permittivity as well as for the negative sign of the imaginary part of an effective permittivity or permeability. This agrees with the Comment of Efros.
We argue, in agreement with our previous work, that periodicity of the metamaterial is responsible for antiresonant behavior of the effective permittivity as well as for the negative sign of the imaginary part of an effective permittivity or permeability. This agrees with the Comment of Efros.
