讲座内容与时间：

1. Introduction to EMATs and Lorentz for generation (12月9日周五15:30-17:00)

An introduction to the general use of EMATs and an explanation of how EMATs generate and detect ultrasonic signals. Some of the theory will be explored.

2. Introduction to magnetostriction with EMATs (12月9日周五19:00-20:30)

An introduction to the general use of magnetostriction and how EMATs generate and detect ultrasonic signals by magnetostriction. Some of the theory will be explored.

3. EMAT applications (rail inspection, crsyatllographic texture measurement, laser-EMAT) (12月12日周一15:30-17:00)

Some typical EMAT applications including rail inspection, measurement of crystallographic texture and laser-EMAT methods)

4. SH guided wave generation with EMATs & applications (12月13日周二15:30-17:00)

SH guided waves generated by EMATs - an overview of SH bulk and guided wave generation by EMATs and some applications that demonstrate the potential of SH wave NDT using EMATs, including weld inspection and the testing of complex shaped parts.

5. Eddy current NDT (12月13日周二19:00-20:30)

2 part talk giving an introduction to Eddy currents. The talk will explain how Maxwell's equations relate to eddy current testing and a basic introduction into how eddy current sensors work

6. High frequency eddy current inspection & near electrical resonant testing (12月14日周三15:30-17:00)

Examples of eddy current applications, focusing on some new and novel approaches using very high frequency eddy current probes and performing eddy current testing using near electrical resonance.
