  • Design and Performance of a Low-Frequency Cross-Polarized Log-Periodic Dipole Antenna 
    Sasikumar Raja, K; Kathiravan, C; Ramesh, R; Rajalingam, M; Barve, Indrajit V (IOP Publishing, 2013-07)
    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. The measured isolation between the two ...
  • High-resolution, high-sensitivity, ground-based solar spectropolarimetry with a new fast imaging polarimeter: I .Prototype characterization 
    Iglesias, F. A; Feller, A; Nagaraju, K; Solanki, S. K (EDP Sciences, 2016-06)
    Remote sensing of weak and small-scale solar magnetic fields is of utmost relevance when attempting to respond to a number of important open questions in solar physics. This requires the acquisition of spectropolarimetric ...
  • A new three-band, two beam astronomical photo-polarimeter 
    Srinivasulu, G; Raveendran, A. V; Muneer, S; Mekkaden, M. V; Jayavel, N; Somashekar, M. R; Sagayanathan, K; Ramamoorthy, S; Rosario, M.; Jayakumar, K (Astronomical Society of India, 2014-09)
    We designed and built a new astronomical photo-polarimeter that can measure linear polarization simultaneously in three spectral bands. It has a Calcite beamdisplacement prism as the analyzer. The ordinary and extra-ordinary ...
  • NLST: India's National Large Solar Telescope 
    Hasan, S. S; Soltau, D; Kärcher, H; Süß, M; Berkefeld, T (Wiley-Blackwell, 2010-06)
    This article introduces the new Indian 2 m telescope which has been designed by MT Mechatronics in a detailed conceptual design study for the Indian Institute of Astrophysics, Bangalore. We describe the background of the ...
