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 ...

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).

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 ...

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 ...
