Mathematical Formulations
The single vegetative obstruction model is formally expressed as,
where, A = The Attenuation due to vegetation. Unit: decibel(dB).
d = Depth of foliage. Unit: Meter (m).
= Specific attenuation for short vegetative paths. Unit: decibel per meter (dB/m).
Ri = The initial slope of the attenuation curve.
Rf = The final slope of the attenuation curve.
f = The frequency of operations. Unit: gigahertz (GHz).
k = Empirical constant.

Famous quotes containing the word mathematical:
“An accurate charting of the American woman’s progress through history might look more like a corkscrew tilted slightly to one side, its loops inching closer to the line of freedom with the passage of time—but like a mathematical curve approaching infinity, never touching its goal. . . . Each time, the spiral turns her back just short of the finish line.”
—Susan Faludi (20th century)
