Integral equations for nonlinear structures of electrodynamics

In recent times there have been many investigations and uses of electromagnetic structures (ES) with nonlinear media and devices. The simplest electrodynamic model for a nonlinear device is the introduction of nonlinear boundary conditions. The linear composite (or complex) anisotropic and bianisotropic media present another field of interest. As these media may be nonlinear, it it interesting to develop the model which describes all these cases. This is the goal of the paper, which is achieved using the integral equation.
