Abstract
Some EMAT coils can be made by handwork. A more sophisticated method is to use the printed circuit technique. An EMAT is regarded as a coil element in the electric circuit, and impedance matching is required for improving EMAT’s transduction efficiency. This chapter describes how to fabricate EMAT with examples. Some designs for impedance-matching circuit are also given.
