For the first time, spin waves, also known as magnons, have been directly observed at the nanoscale. This breakthrough was ...

In this article, the Cramér–Rao lower bounds (CRLBs) for unbiased estimators of sampled real-valued sine-wave parameters are analyzed. Sine-wave frequency is assumed either known or unknown, and both ...

A Ka-band sheet beam high power traveling wave tube based upon sine waveguide slow wave structure is studied. In this paper, phase velocity tapering technology is applied to improve electronic ...

While the operational differences between chorus and flanging are similar, the outputted effects of flanging can sound very harsh, particularly if compared to the mellow sound of a nice chorus. Hence, ...
