Abstarct. Interaction of
electromagnetic waves propagating at the first and second harmonics of a
dominant frequency inside two-dimensional non-linear electromagnetic crystal
with non-linear capacitors is considered. Regime of a spatial synchronism of
two waves at the first and second harmonics is studied. Conditions of spatial
synchronism realization in electromagnetic crystal are investigated. An
approximate model of electromagnetic crystal in form of a system of non-linear
differential equations is proposed. Several selected solutions of the system
are analytically studied. Results of numerical experiments are presented.
Keywords: electromagnetic crystal,
non-linear waves, spatial synchronism.
