Phonon lasers unlock ultrabroadband acoustic frequency combs

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Frequency- and Angle-Domain RCS Extrapolation of Cluster Targets Based on Physics-Informed Stacking Framework

Abstract: This paper presents a physics-informed stacking framework (PISF) for extrapolating the frequency-dependent radar cross section (RCS) of cluster targets. A stacked ensemble model is ...
