Abstract

In order to realize power supply method with less current/voltage fluctuation, new wiring technology using power supply/ground paired transmission lines with low characteristic impedance (Z_o) is propose, and its possibility is examined. This new technology is based on the concept of ldquometamaterialrdquo, and is expected that Z_o of the transmission lines will decrease to less than several ohms by the coupling effect of the surface plasmon and magnon interaction with lines. It is found that the transmission lines covered with a metamaterial sheet exhibit lower Z_o than that of lines with metal sheet. This result suggests the feasibility to reduce characteristic impedance to several ohms in the power supply/ground paired transmission lines for power supply method in high clock frequency.
