A recent study examined a transparent material used in high-impact applications such as helicopter windshields at the ...
Engineers and materials scientists have long recognized that human bone, when compared to structural steel on a weight-adjusted basis, delivers superior strength. Cortical bone achieves compressive ...
Researchers at ETH Zurich have developed a method that uses a single ion to detect electromagnetic fields above a surface and to create a three-dimensional map of them. In the future, this approach ...
Inverse Design Method for Horn Antennas Based on Knowledge-Embedded Physics-Informed Neural Networks
Abstract: This letter aims to overcome the challenges faced by physics-informed neural networks (PINNs) in metal structure design. Taking the design of horn antennas as an example, we propose ...
Abstract: This work introduces a fabrication method for Cavity-SOI substrates featuring grid-structured cavities in the device layer. The effectiveness of this structure was demonstrated through its ...
