Abstract :
Left-handed materials are commonly analyzed by using frequency-dependent parameters that include regions of negative permittivity and negative permeability in Maxwell´s equations. An alternative approach is presented where both right-handed and left-handed behavior are supported by augmenting Maxwell´s equations with additional terms. The proposed equations exhibit typical metamaterial behavior, including frequency bandgap and dispersion.
