  • Observations and interpretation of solar decameter type IIIb radio bursts 
    Krishan, V; Subramanian, K. R; Sastry, Ch. V (Kluwer Academic Publishers, 1980-06)
    Solar decameter bursts of Type IIIb are observed with a multichannel radiometer at wavelengths around 12m. The time and frequency resolutions were 10 ms and 100 kHz. Observations on the time structure of these bursts are ...
  • On the simultaneous existence of eastward and westward flowing equatorial electrojet currents 
    Rastogi, R. G (Indian Academy of Sciences, 1975-02)
    Experimental data on daily variations in the geomagnetic field are analyzed for evidence of counterflowing electrojets. In particular, the disappearance of the q type of Es layer (Es-q) and the appearance of blanketing-type ...
  • Radiation from an electron beam-magnetoplasma 
    Krishan, V (Institute of Physics, 1980-08)
    The possibility of direct generation of electromagnetic radiation at and near electron plasma frequency from an electron beam-magnetoplasma system is explored. The role of the electron beam is replaced by the electron ...
  • Rapid polarization variability in intense sources 
    Gangadhara, R. T; Krishan, V (The American Astronomical Society, 1995-02)
    We have recently reported the polarization changes of the intense electromagnetic radiation, in active galactic nuclei and pulsars, due to stimulated Raman scattering. In this paper, we show that the incident and the ...
  • Transient composite electric field disturbances near dip equator associated with auroral substorms 
    Sastri, J. H; Ramesh, K. B; Rao, H. N. R (American Geophysical Union, 1992-07)
    Ionosonde data of Kodaikanal (Geog.Long. 77° 29′E, dip 3.0°N) and Huancayo (Geog.Long. 75°18′W, dip 2.0°N) are used to show the simultaneous occurrence of a transient disturbance in F region height of composite polarity ...
