Electromagnetic waves propagation in dust storms at millimetre wave band

The effects of dust storms on propagation of electromagnetic wave at millimeter wave band are investigated. The propagation at millimeter wave band is affected by dust particles by way of signal attenuation. Formula for evaluating the wave attenuation at higher frequencies in a dusty medium is the...
