PROPAGATION FEATURES OF H-GUIDES WITH BIANISOTROPIC SPLIT RING RESONATOR METAMATERIALS

Different dispersion properties are imparted to H-guides by split ring resonator metamaterials. Both longitudinal-section magnetic (LSM) and longitudinal-section electric (LSE) modes are capable of propagating very slowly due to metamaterial bianisotropic effects. Enhanced energy flow in the proposed waveguiding structure is also demonstrated. In addition, some abnormal higher-order LSM and LSE modes, eventually leading to the leakage, may come into existence when metamaterials are double negative. Fortunately, for other LSM and LSE modes, leakage can be reduced due to the magnetoelectric coupling. When the metamaterials are of single negative parameters, leakage elimination can be achieved.
