Technique for Determination of Particulate Matter Pollution in the Atmosphere Using Waveguide Slot Linear Array Antennas: A Feasibility Study

Particulate atmospheric pollution alters the dielectric coefficient of the atmosphere. In principle, this could allow pollution to be measured via its effects on the performance of an antenna. In this letter, a novel technique for measuring these effects, based on the use of an optimized air-filled waveguide-fed slot linear array, is shown.
