IEEE ultrasonics, ferroelectrics, and frequency control society

control. The scope of interest of the Society shall include the theory, technology, materials, and applications relating to: (1) the generation, transmission, and detection of mechanical waves and vibrations and their interactions with other phenomena; (2) medical ultrasound, including hyperthermia, bioeffects, tissue characterization and imaging; (3) ferroelectric, piezoelectric, and piezomagnetic materials, including crystals, polycrystalline solids, films, polymers, and composites; (4) frequency control, timing and time distribution, including crystal oscillators and other means of classical frequency control, and atomic, molecular and laser frequency control standards. Areas of interest range from fundamental studies to the design and/or applications of devices and systems within the general scope defined above. All members of the IEEE are eligible for membership in the Society and will receive this Transactions upon payment of the annual Society membership fee of $20.00. Besides receipt of this Transactions, an indirect benefit of Society membership stems from the support it provides for the organization and continuance of the Society Symposia. These events are internationally recognized as the foremost forums for the presentation of new research and application results in the field.
