We will report our development results of phase-change and ferroelectric thin film processing technologies including sputtering, MOCVD and plasma etching as well as manufacturing processes for PCRAM, FRAM and MEMS/Sensor device applications. Thin-film functional material such as phase-change materials and ferroelectric materials have been utilized to form advanced semiconductor and electronic devices...
High temperature superconducting (HTS) cables achieve large power capacity and low-loss power transmission in a compact package. In a new Japanese national project, Sumitomo Electric Industries, Ltd. is working to develop a 66 kV-5 kArms HTS cable with REBCO wires. One of the important technical targets is to reduce AC loss to less than 2 W/m/ph at 5 kArms. To investigate the effect of wire width...
This paper describes the development of a miniaturized 300-MHz band antenna that is effective for small wireless sensor nodes for human and animal health monitoring. We have proposed a new concept of antenna miniaturization using magnetic materials and optimized the design of the new antenna taking the advantage of 3 dimensional full-wave electromagnetic field simulations. Also, its fabrication process...
