| Outline of Final Research Achievements |
A large density modification can easily be generated in a turbulent plasma. For instance, a number of low density bubbles (or cavitons) can randomly exist in a plasma under the strong Langmuir turbulence. Wave propagation characteristics (even for "linear" waves) of such a bubbly plasma can be quite unusual with respect to those of an ordinary uniform plasma. Anomalous wave properties of bubbly plasmas have been investigated experimentally and computationally. In general, plasmas can be easily disturbed. Therefore, bubbly plasmas can be quite common entities. It is hoped that understanding physical properties of bubbly plasmas can lead to an introduction of a new paradigm to physics of plasmas.
