Abstract

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.
