We evaluated the noise suppression effects of carbon coated permalloy nanorod arrays in porous anodic aluminum oxide on coplanar waveguide. The average diameter and length of the Permalloy nanorods was ∼500 nm and ∼10 nm, respectively. The power loss of the Permalloy nanorods was 85% at 20 GHz (in stop-band frequency) which was higher than that of 0.5-μm-thick NiZn-ferrite film (68%). In the pass band frequency region at around 1 GHz, the signal attenuation of the Permalloy nanorod arrays was lower than that of the NiZn-ferrite film.
