    The Cherenkov effect is usually studied for the case of a point particle. In this work we shall analyze, using two methods, this effect for a point electric dipole. We obtain the radiated energy per unit path length per ...
  • Jimenez, JL; Roa-Neri, JAE; Vargas, P (2007)
    In order to understand the rise of runaway solutions in the radiation reaction problem a mechanical model is used. An alternative demonstration of Daboul's theorem, through Hurwitz's criterion, is given. The origin of ...
  • Jimnez, JL; Roa-Neri, JAE; Villavicencio, M (1999)
    In this work the Cherenkov effect for extended charge distributions isanalyzed using two different methods. In the first method, the Poyntingvector is employed to determine the energy radiated, whereas in the secondone, ...

    It is shown that the condition upsilon > upsilon(p) (omega), which is necessary in order to trigger the Vavilov-Cherenkov effect, determines the interval of radiated frequencies and it alone cannot establish a strong ...
  • Jimenez, JL; Roa-Neri, JAE; Villavicencio, M (2001)
    In this paper the Vavilov-Cherenkov radiation produced by an electromagnetic pulse propagating, unchanged in shape, inside a medium is analysed. The electromagnetic pulse induces a polarization charge which moves inside ...
