Diagnosis of Insulation Materials with Terahertz Wave

Dazhi Li and Shinji Motokoshi
Abstract

Preliminary experiments for a planning project to develop terahertz wave devices for non-contact and non-destructive diagnosis of electric power facilities are presented. A reflection-type terahertz time-domain spectroscopy was built to study the possible applications in diagnosing defects occurred in insulation materials or other nonmetallic parts of electric power facilities.

Electromagnetic and Microwave Absorption Properties of the Carbonyl Iron/Tic Hybrid Powders in the X Band

Hongyu Wang, Dongmei Zhu, Wancheng Zhou and Fa Luo
Abstract

The electromagnetic and microwave absorption properties of the carbonyl iron/TiC hybrid powders are studied in the X band. A favorable microwave absorption property can be obtained by changing the ratio of carbonyl iron (CI) and TiC. When the TiC content was 25%, the hybrid powders have the optimum microwave absorption property. The bandwidth below -20 dB can be obtained in 9.4-10.5 GHz and the minimum reflection loss value was -25.1 dB.

Magnetic Field Effect (MFE) on Heterogeneous Photocatalysis and the Role of Oxygen

Hideyuki Okumura
Abstract

Heterogeneous photocatalysis involves multiple elementary steps at the interphase interface. Although magnetic fields are known to influence photocatalytic reactions, the mechanism is still not clearly understood or agreed-upon. In this short article, the significant roles of oxygen will be discussed, including the involvement of water.
