磁場コンセントレータ付きラム波用電磁超音波探触子の開発

抄録

When a Lamb wave electromagnetic transducer(EMAT) is used to detect different types of defects, any different types of electromagnetic induction coils and magnets are needed to change modes. This study is examined whether it is possible to improve the function of Lamb wave EMAT by combining the same Lamb wave EMAT and a magnetic field concentrator with a different structure.
