Determination of effective permittivity and permeability of metamaterials from reflection and transmission coefficients
Determination of effective permittivity and permeability of metamaterials from reflection and transmission coefficients
We analyze the reflection and transmission coefficients calculated from transfer matrix simulations on finite lengths of electromagnetic metamaterials, to determine the effective permittivity (\ensuremath{\varepsilon}) and permeability (\ensuremath{\mu}). We perform this analysis on structures composed of periodic arrangements of wires, split ring resonators (SRRs), and both wires and SRRs. We find …
