الوصف
The millimeter waves bands are in the short wavelengths range; unfortunately, the shorter the wavelength the more attenuation will be induced by absorption and scattering due to rain drops, dust and sand particles in the radio path . The attenuation caused by sand and dust particles is one of the major problems in the utilization of microwave and millimeter wave bands for terrestrial and space communication . When microwave and millimeter waves pass through a medium containing precipitations like sand and dust particles, the signals gets attenuated through two phenomena:
1- Absorption of energy by sand and dust particles, which depends on the loss tangent of the sand and the dust contents, the more contents of sand and dust material attenuation to the signal, will be move.
2- Scattering of energy out of beam by sand and dust particles.
