Abstract

The electromagnetic excitation of 2D array of bianisotropic particles by plane waves is considered. The array is assumed to be infinite and the particles to be small compared with the wavelength so that the dipole approximation is available. The electromagnetic interaction between tall the particles is taken into account analytically. Two kinds of bianisotropic particles: chiral particles and omega particles are analyzed. Both the electric and magnetic moments of each particle are related to each other and depend on the local field. Therefore, the standard approach used in the theory of scanning antenna arrays cannot be applied. The analytical model under consideration allows to express the electric and magnetic moments induced in each particle through incident wave field amplitudes. These relations are dyadic ones.
