Abstract We consider a electrodynamic modeling of microstrip reflecting structures loaded with nonlinear elements and having a substrate made of a metamaterial instead of a dielectric substrate. Briefly the method of analysis based on the solution of Maxwell"s equations with the given boundary conditions and the radiation condition at infinity was described. The features of setting of nonlinear boundary conditions on the surface of the nonlinear elements, as well as specific analysis of electrodynamic structures using metamaterials were revealed. The results of numerical experiments are given on the basis of which it can be concluded that the use of metamaterials help to improve the reflective properties of the microstrip structures. The approach described in the paper can be considered universal, since it is possible to analyze the effect on the reflective properties of the microstrip structure as non-linear loads, as well as the substrate material. Its implementation can significantly enhance the ability of application of such microstrip devices. Metamaterials were considered in the decision without taking into account losses that might lead to some inaccuracies in the results.
