As cyber threats continue to grow, so does the reality that digital satellite communications can be degraded and denied either through digital or electromagnetic means. If these capabilities are ...

Using wideband technology high frequency communications can offer commensurate or increased data throughput over satellite communications in normal or satellite-denied environments to augment command ...

The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...

Most recent heater-based studies of magnetospheric processes and ionosphere-thermosphere-magnetosphere (ITM) system couplings use the “virtual antenna” concept, which allows generation and injection ...
