Abstract：Some advances on the theory and techniques of Electromagnetic Non-Destructive Evaluation (ENDE) are introduced in this presentation. In view of the NDE of structures of nuclear power plants, fusion reactors, and new materials such as super-light porous material, some recent developments on detection and sizing of macro defects, evaluation of residual stress and material degradation with ENDE method such as the eddy current testing, pulsed eddy current testing, natural magnetization method, magnetic flux leakage method, electromagnetic acoustic transducer, magnetic Barkhausen noise etc. are presented. The design and optimization of probe, high efficient numerical simulation method, quantitative evaluation method, new ENDE method, and the NDE of new material and new structures are introduced. The lecture is mainly related to the research work and results of the NDE group of Xi’an Jiaotong university, in addition with some typical new theoretical and technical advances in ENDE of the global NDT society.
