... 1996: . Using the original method of diagnostics of the Solar corona structure by the effects of radio wave refraction (space-frequency tomography) in the wavelength range of 2-30 cm on the RATAN-600 telescope, the electron density, emission measure and porosity of coronal loops was measured for the first time regardless of the optical data. It is shown that most of the matter is concentrated in the super-dense loops, occupying less than 10% of the total coronal volume. ... Archive . ...
