Abstract

The radio frequency characteristics of Permalloy nanorods' array have been examined by coplanar waveguide (CPW) cell. The Permalloy nanorods' array was grown in anodic aluminum oxide porous templates with a diameter of ∼20 nm. As the Permalloy nanorods' array was placed on CPW, the characteristic impedances of the CPW were changed from 50 to 38 Ω at 1 GHz. The magnitude of inductance was decreased from 3 GHz and the capacitance was increased up to twice in comparison with that of CPW. The signal attenuations were abruptly increased over 1 GHz. The propagation wavelengths due to the insertion of Permalloy nanorods' array were decreased about 30% at 1 GHz in comparison with that of CPW without magnetic materials.
