Fog propagation model
Model the behavior of electromagnetic radiation from a point of transmission as it
travels through fog or clouds  by using a
object. Propagation models for fog are valid from 10 to 1000 GHz, assume line-of-sight (LOS)
conditions, and disregard terrain, the curvature of the Earth, and other
Fog object by using the
Temperature — Air temperature
15 (default) | scalar
Air temperature, specified as a scalar in degrees Celsius (C).
WaterDensity — Liquid water density
0.5 (default) | scalar
Liquid water density, specified as a scalar in grams per cubic meter (g/m3).
Model Coverage in Thick Fog
Display the coverage area for a transmitter in thick fog.
Create a propagation model for fog. Specify the water density as 0.5 grams per cubic meter.
pm = propagationModel("fog","WaterDensity",0.5);
Create a transmitter site. Display the coverage area for the transmitter. Propagation models for fog require transmitter frequencies between 10 and 1000 GHz.
