    Electromagnetic waves dynamics in a nonlinear dielectric slab by the method of characteristics

    No full text
    Electromagnetic shock waves are a relatively unexplored field. This paper considers their propagation in the case of a dielectric slab. At first we examine the mathematical problem relating to the physical interpretation of the uniqueness of the solution. A link between uniqueness and irreversibility is pointed out as in the case of shock waves in gasdynamics. Then we illustrate an algorithm, based on the concept of characteristics curves, which gives a very interesting performance

    The non-uniqueness of the surface integral equations for the scattering from perfectly conducting objects

    No full text
    The problem of non-uniqueness of the surface integral equations adopted for the determination of the current density over perfectly conducting objects is dealt with. Firstly, the subject is reviewed with reference to a circular cylinder. Then, the case of more scattering objects is investigated and both the strategies for the determination of the non-uniqueness conditions and the countermeasures for facing the problems are given
