Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Harmonic clutter recognition and suppression for automotive radar sensors
International Journal of Distributed Sensor Networks, 2017 In this article, we propose a novel harmonic clutter recognition and suppression method to overcome the deterioration of a target- or vehicle-detection performance due to harmonic clutters.

Suppression of higher harmonics at noise induced resonances
Physical Review E, 1995 We consider the generation of higher harmonics in periodically driven noisy nonlinear systems. Recent numerical studies of higher harmonics in such systems have shown so-called noise induced resonances that manifest themselves in a strong suppression of higher harmonics at certain values of the noise level.

A Wideband Filtering Antenna Array With Harmonic Suppression
IEEE Transactions on Microwave Theory and Techniques, 2020 In this work, a wideband 2×2 filtering antenna array is proposed and studied for fixed beam applications. The device is composed of a patch antenna array and a slotline-based four-way filtering power divider served as the feeding network. The integration of the antenna and the feeding parts is not a simple combination but a co-synthesis, where the ...

Rapidly Solidified High‐Strength Invar 36 Prepared by Planar‐Flow Melt Spinning
Advanced Engineering Materials, EarlyView.The Invar 36 alloy was rapidly solidified using the planar‐flow melt‐spinning technique. Ribbon samples with thicknesses ranging from 20 to 160 mm were produced. As the grain size of the ribbon decreased to sub‐micron levels, the hardness increased by more than 2 times.

Advanced Engineering Materials, EarlyView.This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...
