Can a near-field tag communicate with a far-field reader antenna, and vice versa? —Name withheld ——— Passive low-frequency (LF) and high-frequency (HF) RFID tags operate in the near field, while ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240250, discusses on-chip multi-channel near-far field terahertz vortices with parity breaking and active modulation.

Figure 2. UWB DUT Size-Related Near/Far Field EIRP Test Constraints. Conversely, following the same 20-cm line in Figure 2, at 20 GHz, accounting for only the theoretical receiver noise level, the ...

Near-field magnetic (H-field) and electric (E-field) probes let you “sniff” where EMI lurks—around circuits, cables, and enclosures. H-field probes use a conductive loop to detect magnetic fields ...

But since near-field light doesn't reach our eyes like far-field light does, researchers haven't developed a comprehensive toolkit to harness and manipulate the near field.

A research paper entitled "Near-Field Wideband Channel Estimation for Extremely Large-Scale MIMO", was published in SCIENCE CHINA Information Sciences. It is co-authored by Mr. Mingyao Cui (first ...

The near-field results were used to predict far-field performance of the assembly, which includes lenses, filters, a feed horn and baffles. “We developed a way to use radio-holography to characterise ...

You can expect to see more on near- and far-field measurements in a cover story in our upcoming August print issue, which will be distributed at the EMC+SIPI Symposium July 30 through August 3 in ...
