In this work we analyse the Cherenkov effect for non-rotating extended charges. We obtain the energy radiated per unit path length per unit frequency by the charge facing the Cherenkov effect as a radiation reaction problem. ...

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, ...

Using the mathematical concept of eutactic star, we prove that it is possible to define a morphospace for irregular echinoids by using a single parameter. In particular, we have found an extraordinary geometric property ...

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 ...
