Intra-body Communication Using Ultrasonic Wave Propagation

With advances in technology and people’s increasing emphasis on health issues, there has been a rapid development of wearable and implantable biomedical sensors. However, radio frequency waves dominate wireless communications, despite disadvantages such as high attenuation in the human body, considerable power consumption, and complicated wireless antenna design, which has hampered the developm...

Simulation of the ultrasonic wave propagation in solids

Historically, nondestructive testing (NDT) has been used for detecting macroscopic and microscopic discontinuities in structures after they have been in service for some time or in new ones. The prominent role in nondestructive testing ultrasonic has won because of the application versatility, sensitivity and convenience. It has become evident that it is practical and cost effective to expand t...
