GPR

    A comprehensive approach to electromagnetic field modeling in relationton to non-destructive evaluation is presented for  the first time in this text. Its purpose is to allow students to model and represent fields that would not be solvable by any other means, in order to understand the various aspects of non-destructive testing of materials.
    The book begins reviewing electromagnetics in  general  before moving on to analytical methods ofcomputation.  This approach allowsthe contrast between analytical and numerical methods to be illustrated with the limitations of analytical methods being viewed as the starting point for numerical methods. The text then deals with the general  methods of finite differences and finite elements,  examines elliptical processes, introduces parabolic partial  differential equations and their applications in transient methods of testing, deals with  hyperbolic partial differential equations and their use in the modeling of wave propagation in the time domain and finally describes some numerical methods required for the application of  techniques previously outlined.
    Each chapter has a number of problems designed to review the material and expand upon it.  Most of the problems are simple
enough  to be  solved  as assignments,  but realistic enough to
allow extension  to testing geometries of interest to the reader.
    Consequently, this will be a valuable text for senior undergraduates and graduates of electrical engineering and engineering technology as well as researchers in NDE and electromagnetics. Practitioners of NDE and professional  engineers involved in design and production of  electromagnetic  devices who are  interested in expanding their understanding of  numerical solutions to NDE problems will also find this text useful.
