Title: | The role of a specific response of media in the Vavilov-Cherenkov effect |
Authors: | Roa-Neri, JAE Jimenez, JL Villavicencio Torres, Mirna |
Issue Date: | 2006 |
Abstract: | 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 restriction to the velocity of the particle. It is exhibited that it is possible to define a general lower bound for the velocity of the particle, which does not depend on the frequency when both, a specific response of the medium is taken into account and the mentioned condition is considered. The minimum value of the phase velocity of light in the medium determines the existence of such general lower bound. |
