Radio amateurs are inventive people, and though not all of them choose to follow it there is a healthy culture of buildng radio equipment among them. In particular the field of antennas is where ...

Moreover, the proposed algorithm resolves multiple sources without the priori knowledge of signal information, suffers no ambiguity in the estimation of the Poynting vector, and pairs the x-axis ...

The Poynting vector is frequently utilized for extracting propagation vector information owing to its adaptability, efficiency, and fine angular resolution (Zhang et al., 2010; Yan and Dickens, 2016).

Because of the strong magnetic field of one or both binary members and high orbital frequencies, these binaries are strong sources of energy in the form of Poynting flux (e.g. magnetic-field-dominated ...

The best free Adobe Illustrator alternatives serve up all the essential tools artists need for vector editing without requiring a Creative Cloud subscription. There's ...

Practical low-loss metamaterials at optical frequencies may soon be realized thanks to optical parametric amplification that uses backwards propagation of a signal beam in negative-index ...
