Abstract. Problems of mathematical
modeling and multi-criteria optimization of two-dimensional artificial medias
on the base of dielectric slab with isotropic metal strip grids on its surfaces
are considered. Approximate equivalent impedance boundary conditions are
introduced for description of the grid located between two medias. A model that
takes into account dissipative loss in the grid is proposed. Dispersion
equations relatively propagation constants of eigen modes of dielectric slab
with grids are obtained. Quality factors of artificial medias are introduced.
These factors allow one to evaluate efficiency of artificial medias application
in devices of microwave integral optics. Results of numerical experiments
oriented to optimization of artificial medias are presented.
Keywords: metamaterial, frequently periodical
array, eigen mode, microwave optics.
