Design and performance of a low frequency cross-polarized log-periodic dipole antenna
K. Sasikumar Raja, C. Kathiravan, R. Ramesh +2
We report the design and performance of a cross-polarized log-periodic dipole (CLPD) antenna for observations of polarized radio emission from the solar corona at low frequencies.…
An estimate of the magnetic field strength associated with a solar coronal mass ejection from low frequency radio observations
K. Sasikumar Raja, R. Ramesh, K. Hariharan +2
We report ground based, low frequency heliograph (80 MHz), spectral (85-35 MHz) and polarimeter (80 and 40 MHz) observations of drifting, non-thermal radio continuum associated wit…
Low frequency observations of transient quasi-periodic radio emission from the solar atmosphere
K. Sasikumar Raja, R. Ramesh
We report low frequency observations of the quasi-periodic, circularly polarized, harmonic type III radio bursts whose associated sunspot active regions were located close to the s…
Amplitude of solar wind density turbulence from 10--45
K. Sasikumar Raja, Madhusudan Ingale, R. Ramesh +3
We report on the amplitude of the density turbulence spectrum () and the density modulation index () in the solar wind between and . We derive t…
