On the possibility of radio observations of current sheets on the Sun

The possibility of a discovery of current sheets in the radioband by using their screening and reflective properties as also their own emission is discussed. It is shown that the thermal bremsstrahlung of the sheet may be of a sufficiently large intensity (tausub(s)>I) on the maximal critical frequency for the plasma in the sheet. In dependence from electron density and temperature the thickness of the sheet from tens centimetres to hundreds metres is sufficient to provide optical depth tausub(s)>=I. Spectral observations with sufficient angular resolution may give such characteristics of the sheet as its temperature, electron density, thickness and height in the solar atmosphere. (Auth.)
