Analysis of nonlinear microstrip lattice with metamaterial substrate using method of integral equations

摘要

The problem of scattering of plane electromagnetic wave on the infinite microstrip lattice with nonlinear loads in the strip plane was solved with help of integral equations method, when a metamaterial (MM) is used as lattice substrate. It is shown that application of MM in microstrip lattice as a substrate (instead of a dielectric) provides alignment of levels of the higher harmonics in comparison with first harmonic in the reflected field. It is reached due to suppression of fundamental harmonic in the reflected field.
