摘要
We begin with Maxwell's eqnations and put the thin electric resonance dielectric sheet eqnivalent into electric surface current. Using periodic boundary conditions and the principle of superposition, we can get the dispersion relation and Bloch impedance of periodic electric resonator metamaterials. Base on the dispersion relation and Bloch impedance, we can obtain the theoretical analytical expressions of Bloch constitutive parameters. Since we consider the impact of the magnetic antiresonance, we find theoretical predictions match the retrieval results very well, which showed that the analytical expression derived in the paper is extremely effective.
