| Abstract(in English) | The ferrite resonator, used for the NRD guide circulator to date, consists of a Teflon tube sandwiched by two Ni-Zn circular ferrite disks. In this structure, the Teflon tube has to be made by accuracy of less than several micron-meter orders, and thus, the cost of the ferrite resonator may increase. With this in mind, a new type of ferrite resonator, using a Teflon cylinder instead of the Teflon tube, was investigated. The Teflon cylinder can be easily fabricated, and hence, the cost reduction. The new ferrite resonator was analyzed based on a 3-dimensional finite-element method. The circulator constructed by this ferrite resonator was fabricated and its performances were tested. From this result, it was obvious that agreement between the measured and calculated resonance frequencies was quite satisfactory, and thus the simple-structure and low-cost NRD guide circulator was successfully developed. |
