Ultrasonic communication is a desirable method for information transfer through solid
channels such as metallic bars, plates, or pipes by overcoming the physical barriers that …

Acoustic waves can be used for wireless telemetry as an alternative to situations where
electrical or optical penetrators are unsuitable. However, the response of the ultrasonic …

Ultrasonic communication through solid channels suffers from wave dispersion, attenuation,
and multipath effect. It can be observed that the channel is frequency selective, and some …

Third-party and expert analysis is a cost-effective solution for solving specialized problems
or processing large datasets related to reactor structural health monitoring and …

We show that as a side effect of building code requirements, almost all commercial buildings
today are vulnerable to a novel data exfiltration attack, even if they are air-gapped and …

This dissertation investigates batteryless sensor nodes embedded in metal structures,
focusing on acoustic backscatter, active communication, and wireless power transfer. In …

Ultrasonic communication is proven to be reliable for transmitting data, images, and video
streams through solid channels to overcome certain physical barriers which prevent …

This dissertation identifies and addresses new data security problems for manufacturing
environments and their associated commercial office spaces. The work includes novel …

This paper presents an adaptive equalizer design for high-rate ultrasonic communication
through solid channels. Ultrasonic communication through solid channels is prone to …

Nuclear facilities are partitioned into different blocks, and all equipment therein is well-
packed for isolation purposes. The primary barriers of each block include a thick, reinforced …
