In ultrasonic pulse-echo systems, polymers like PMMA (polymethylmethacrylate) and PEEK
(polyetheretherketone) are often used as buffer-rods, placed between the ultrasound …

Sandwiched piezoelectric transducers are widely used, especially in high power
applications. For more convenient analysis and design, a PSpice lossy model of …

Pulsed electroacoustic (PEA) method is a very popular method for measurement of charge
in dielectrics. In this method, an acoustic wave proportional to charge is generated by a …

Ultrasonic waves at 1 MHz are used to send information across solid walls without the needs
for through wall penetrations. A communication channel is established by attaching a set of …

The equivalent circuit simulation plays an important role in the design of ultrasound
transducer. However, the existing methods are difficult to achieve the effect of matching and …

In the field of high-voltage transmission systems, different degradation phenomena affect the
reliability of the employed components. In particular, under dc stress, the space charge …

Ultrasonic power and data transfer through multilayered curved walls was investigated using
numerical and experimental analysis. The acoustic channel used in this paper was formed …

The need to transmit digital information across metallic barriers arises frequently in industrial
control applications. For example, radio frequency sensing and control networks deployed …

This report outlines the preliminary design of the DSTO Acoustic Electric Feedthrough (AEF)
Laboratory Demonstrator Mk II which will pass power, and transfer data, through metal plate …

Quantitative modeling of ultrasound measurement systems is of considerable value for
design, analysis, and interpretation of measurements, methods, and systems. In this work, a …
