The Thomas-Fermi method has been applied to the problem of screening due to an electron gas confined to a filament and a coaxial infinite cylinder. Using parameters derived for K2Pt(CN)4Cl0.32·2.6H20, the potential in the region between the filament and cylinder due to a source charge in the filament was evaluated and was found to vary approximately as e-keffrr with an effective screening length about ten times that of metallic platinum. The isotropic form of the screened potential shows the close relationship to screening in three dimensions.
