Outline of Final Research Achievements

A near field magnetic antenna device using a ferromagnetic resonance states in magnetic thin film was studied for the application of wireless 3D semiconductor chip integration over 10 GHz. The devices, which consist of micro-patterns of FeCo thin film on a coplanar wave guide, were made for the study of the conditions to obtain a large impedance change. As a result, the largest variation for the impedance change by ferromagnetic resonance was achieved by putting the ferromagnetic materials onto the edge of the signal line. The transmission properties inter fabricated devices were also measured. Small electric power transmission were also observed in a frequency band over 10 GHz where the device was in a ferromagnetic resonance state.
