Nonthermal Food Processing Technologies: A Comprehensive Review
Future Postharvest and Food, EarlyView.The graphical abstract illustrates the shift from traditional thermal food preservation methods to advanced nonthermal technologies. Traditional methods, represented by heating, often compromise the nutritional and sensory quality of foods. In contrast, nonthermal approaches such as high‐pressure processing (HPP), pulsed electric field (PEF ...

Magneto-inductive Passive Relaying in Arbitrarily Arranged Networks
, 2017 We consider a wireless sensor network that uses inductive near-field coupling for wireless powering or communication, or for both. The severely limited range of an inductively coupled source-destination pair can be improved using resonant relay devices ...

A tunable microwave absorption metamaterial inspired by moths evading bat detection
InfoMat, EarlyView.Electromagnetic radiation in the current environment has become complex and uncontrollable due to the advancement of wireless technology. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial incorporating broadband and tunable microwave absorption properties combined with deep learning algorithms.

Laser &Photonics Reviews, EarlyView.A heterogeneous III‐V/SiN platform for lasers at 800 nm is realized using the micro‐transfer printing method. Efficient GaAs gain sections are directly butt‐coupled to SiN waveguides, enabling continuous‐wave and mode‐locked extended‐cavity lasers. The mode‐locked lasers generate highly stable pulse trains with repetition rates up to 9.2 GHz and a ...

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

International Journal of Emerging Engineering and TechnologyThe concept of wireless power transmission was first proposed by Nikola Tesla. He suggested that he could transfer power through the air. The radio waves and microwaves in the air are captured by the antenna and transferred to the destination.
