The electrodynamic analysis of a
nonlinear microstrip lattice with a metamaterial substrate on the basis of the
solution of Maxwell's equations with the given boundary conditions and a
radiation condition is considered. Singularities in compilation of a system of
nonlinear integral equations due to use of a metamaterial substrate are shown.
Numerical results are presented in the form of dependences of reflection
coefficients on the main and the multiple harmonics from parameters of
nonlinear loads. The constructive synthesis of the geometrical sizes of the
microstrip elements allowing to increase functioning
efficiency of a reflective
lattice due to increase
of the reflected field on the multiple harmonica is also provided.
Key words: nonlinear scattering , microstrip array, metamaterials, electrodynamic analysis, constructive synthesis.
