Soft Metalens for Broadband Ultrasonic Focusing through Aberration Layers

Nature Communications
Aberration layers (AL) often present significant energy transmission barriers in microwave engineering, electromagnetic waves, and medical ultrasound. However, achieving broadband ultrasonic focusing through aberration layers like the human skull using ...

Piloting the BlueROV2 Using an Xbox Controller Over Acoustic Communication via ROS2

openUnderwater vehicles are typically piloted through wired tethers, which limit range, maneuverability, and deployment flexibility. Acoustic communication offers a promising alternative, but its constraints—low bandwidth, high latency, and packet loss ...

Determining and testing the optimal pure-tone frequency for use in acoustic conditioning of free-ranging common carp (Cyprinus carpio)

, 2012
Pure-tone frequencies of 400, 700, and 1000 Hz were tested to determine which achieved the strongest response when used in conditioning experiments on captive common carp (Cyprinus carpio) for the purpose of determining the most effective frequency to ...
