Abstract—Microwave propagation in dust storms has become an active research field. Dust particles’ permittivity property is an important component with its applications in microwave signal propagation. Permittivity values, determined using different techniques and methods, usually serve as input variables to computation of electromagnetic scattering. They are also used to determine propagation impairments such as microwave attenuation, phase rotation, cross polarization, antenna’s accretion and beam shift effects thereby making accurate knowledge of dust permittivity in the microwave frequency range very important. This paper has investigated and presented a review of some related works on the permittivity of dust particles. The current state of knowledge of dust particles permittivity is presented by examining the variety of techniques and methods, their strengths and limitations. The permittivity properties of dust samples are a function of frequency, moisture content and chemical composition. Identical chemical composition of dust sample gives identical permittivity, while different chemical compositions give a different permittivity property. Furthermore, gaps in knowledge that need to be covered are identified and the projected path and outlook of dust particle’s permittivity property is also presented.
