On a singular limit problem for nonlinear Maxwell's equations

Abstract

In this paper we study the following nonlinear Maxwell's equations \\ $\varepsilon \E_{t}+σ(x,|\E|)\E= \g \vh +\F,\, \vh_{t}+\g \E=0$, where $\sigma (x,s)$ is a monotone graph of $s$. It is shown that the system has a unique weak solution. Moreover, the limit of the solution as $\epsilon \to 0$ converges to the solution of quasi-stationary Maxwell's equations.
