Slow wave propagation in nonradiative dielectric waveguides with bianisotropic split ring resonator metamaterials

Different dispersion properties are imparted to nonradiative dielectric (NRD) waveguides by split ring resonator metamaterials. Both longitudinal section magnetic and longitudinal section electric modes are capable of propagating very slowly due to the metamaterial bianisotropic effects, and can even approach zero velocity under certain condition. Enhanced energy flow in the considered structure is also demonstrated. Finally, miniaturization of NRD waveguide based on these unusual properties is proposed.
