Department of Information & Communication Engineering, Kyungsung University, Busan 608-736, Korea(Received 6 February 2015, Received in final form 16 February 2015, Accepted 16 February 2015)In this paper, a magneto-inductive wave generated in a chain of LC resonators fabricated with Ni-Zn ferrite cores and chipcapacitors is presented. RF signal propagates to neighbor resonator one by one as a consequence of the magnetical coupling betweentwo resonators in the device. The magnetical coupling is due to the mutual inductances along the chain of resonators. So, the signalamplitude (≈ coupling intensity) is dependent of the mutual inductance which can be adjusted by applied magnetic field. In order todemonstrate the device, some experiments have been carried out systemically. The transmission characteristics of a magneto-inductivewave could be controlled by applied external magnetic field. The device composed of 5 resonators; the center frequencies wereestimated to be 32 MHz and 38 MHz with the external magnetic flux density of 75 Oe and 222 Oe, respectively. We expect that thereported results could open a promising way to a high variety of applications in one- and two-dimensional functional devices, such astransducers, delay lines, power dividers and couplers.Keywords: magneto-inductive wave, ferrite core, periodic chain
