Phase correction for Learning Feedforward Control [PDF]

Proceedings 2003 IEEE/ASME International Conference on Advanced Intelligent Mechatronics (AIM 2003), 2003
Intelligent mechatronics makes it possible to compensate for effects that are difficult to compensate for by construction or by linear control, by including some intelligence into the system. The compensation of state dependent effects, e.g.

Aberration correction in abdominal histotripsy

International Journal of Hyperthermia, 2023
In transabdominal histotripsy, ultrasound pulses are focused into the body to noninvasively destroy soft tissues via cavitation. However, the ability to focus is limited by phase aberration, or decorrelation of the ultrasound pulses due to spatial ...

Optimizing Metasurface-Component Performance by Improving Transmittance and Phase Match of the Nanopillars

Nanomaterials, 2022
In the propagation phase of a dielectric metasurface, there are two important problems. Firstly, the range of transmittance of the nanopillars for a building metasurface is usually between 60% and 100%, which reduces the metasurface’s overall ...
