原始语种摘要: Abstract(#br)The electromagnetic wave (EMW) transmittance in sand/dust storms is studied via Monte Carlo (MC) simulation and the effect of charged particles and multiple scattering processes on the EMW transmittance/attenuation in sand/dust storms is studied. Based on Monte Carlo simulation, the electromagnetic wave propagating in a sand/dust storm is treated as Monte Carlo photon (MCP) packets, which are randomly scattered by sand/dust particles. The MC simulation results show that neglecting the multiple scattering effect could result in significant error in the theoretical evaluation of EMW transmittance/attenuation in sand/dust storms, especially at high frequency bands and under low visibility conditions. As the sand particles are charged, this error could be enlarged further....
