The original version has been complemented with selected ideas on ultrasonic measurement that have emerged since the first edition was released. The book is divided into four parts: PART I offers a self-contained description of the basic elements of coupling mechanisms along with the practical designing of EMATs for various purposes. Several implementations to compensate for EMATs? low transfer efficiency are provided, along with useful tips on how to make an EMAT. PART II describes the principle of electromagnetic acoustic resonance (EMAR), which makes the most of EMATs? contactless nature and is the most successful amplification mechanism for precise measurements of velocity and attenuation. PART III applies EMAR to studying physical acoustics. New measurements have emerged with regard to four major subjects: in situ monitoring of dislocation behavior, determination of anisotropic elastic constants, pointwise elasticity mapping (RUM), and acoustic nonlinearity evolution. PART IV deals with a variety of individual issues encountered in industrial applications, for which the EMATs are believed to be the best solutions. This is proven by a number of field applications. 410 0$aSpringer Series in Measurement Science and Technology,$x2198-7807 606 $aElectronic circuits 606 $aMaterials science 606 $aAcoustics 606 $aAcoustical engineering 606 $aElectronic Circuits and Devices$3https://scigraph.springernature.com/ontologies/product-market-codes/P31010 606 $aCharacterization and Evaluation of Materials$3https://scigraph.springernature.com/ontologies/product-market-codes/Z17000 606 $aAcoustics$3https://scigraph.springernature.com/ontologies/product-market-codes/P21069 606 $aEngineering Acoustics$3https://scigraph.springernature.com/ontologies/product-market-codes/T16000 615 0$aElectronic circuits. 615 0$aMaterials science. 615 0$aAcoustics. 615 0$aAcoustical engineering. 615 14$aElectronic Circuits and Devices. 615 24$aCharacterization and Evaluation of Materials. 615 24$aAcoustics. 615 24$aEngineering Acoustics. 676 $a621.3815 700 $aHirao$b Masahiko$4aut$4http://id.loc.gov/vocabulary/relators/aut$0825088 702 $aOgi$b Hirotsugu$4aut$4http://id.loc.gov/vocabulary/relators/aut 906 $aBOOK 912 $a9910148794003321 996 $aElectromagnetic Acoustic Transducers$92102293 997 $aUNINA
