Nondestructive evaluation (NDE) is the process of examining the integrity of a material without impairing its future usefulness and is quite naturally formulated in the context of inverse problems. In the case of electromagnetic probes, these inverse problems will involve solving Maxwell’s equations at some level. Consequently we can anticipate computational algorithms that are time and computer memory intensive. Our motivation is to develop on-line, real-time algorithms to be used in portable testing devices, requiring the use of reduced order computational ideas. Hence, this talk focuses on such a computational method based on reduced order proper orthogonal decomposition (POD) methods.
