  • Plant alkali content and radio wave communication efficiency in high intensity savanna wildfires 

    Mphale, K.M.; Heron, M.L. (Elsevier Science Ltd. www.elsevier.com/locate/jastp, 2007)
    The flames of wildfires are weakly ionized gas. The ionization is mainly due to omnipresent alkali and alkaline earth metal species that are emitted from thermally decomposing plant structure into the flame during a ...

  • Radio wave propagation experiment in sugarcane fire environments 

    Letsholathebe, Douglas; Mphale, Kgakgamatso M.; Chimidza, Samuel; Heron, Malcolm L. (Scientific Research Publishing Inc., https://www.scirp.org/journal/jemaa/, 2016-07-21)
    Large fires have an effect of suppressing Very or Ultra High Frequency (VHF/UHF) radio wave signals strength which consequently impact negatively on the efficiency of radio communications at the frequency ranges. Mobile ...
