Abstract: Transducers fabricated from sol-gel composites are used in high-temperature non-destructive evaluation because of their suitable frequency range, high-temperature stability, thermal-cycle durability, high signal-to-noise ratio, broadband frequency characteristics, good acoustic bonding and curved-surface conformability. Generally speaking, units in the 100-200 watt range are sufficient for shallow water use and units up to 1,000 watts and more may be necessary to probe deep canyons and drop-offs. Typically, they have small footprints and the frequency varies in the range of 3.5Mhz – 11.5Mhz. %���� Systems typically use a transducer which generates sound waves in the ultrasonic range, above 18 kHz, by turning electrical energy into sound, then upon receiving the echo turn the sound waves into electrical energy which can be measured and displayed. The transducers are also useful in emergency and mobile settings, as they are portable and lightweight. In all materials, attenuation increases with temperature, so at elevated temperatures the maximum measureable thickness will normally be lower, especially in plastics. Usually a transducer converts a signal in one form of energy to a signal in another. The frequency range of EHF ranges from 30 GHz to 300 GHz.
