Impact of inherent periodic structure on effective medium description of left-handed and related metamaterials
We study the frequency dependence of the effective electromagnetic parameters of left-handed and related metamaterials of the split ring resonator and wire type. We show that the reduced translational symmetry (periodic structure) inherent to these metamaterials influences their effective electromagnetic response. To anticipate this periodicity, we formulate a periodic effective …
