  • Pipe electromagnetic field simulation apparatus using Born's approximation rule
    Patent number: 5270647
    Abstract: A pipe electromagnetic field simulation apparatus used to simulate a current produced by flaw in a pipe when the flaw is subjected to the electromagnetic field of a transmitting coil. The apparatus includes a system for determining an electromagnetic field distribution of a represented pipe without a flaw, a system for determining an equivalent current source of a represented flaw in the represented pipe, and a system for determining the electromagnetic field distribution of a represented pipe with a flaw. The apparatus may also include a system for determining a signal received by a detector which indicates a flaw.
