Anomalous propagation ( shorten as Anoprop) includes different forms of electromagnetic (EM) wave propagation that are not encountered in a standard atmosphere due to a non standard distribution of temperature and humidity with height in the atmosphere. While technically the term includes propagation with larger losses than in standard atmosphere, in practical applications it is most often meant to refer to cases when signal propagates beyond normal radio horizon.
Famous quotes containing the word anomalous:
“Before the land rose out of the ocean, and became dry land, chaos reigned; and between high and low water mark, where she is partially disrobed and rising, a sort of chaos reigns still, which only anomalous creatures can inhabit.”
—Henry David Thoreau (1817–1862)
