In the innovative optoelectronics, negative-dielectrics ND are considered as promising materials. Metals, like silver and gold, are ND in visible light and near- infrared range. The goal of the present paper is to study the problems of the plane wave scattering of light by a thin flat grating made of penetrable ND strips or of impenetrable strips covered with ND from one or both sides. Strip gratings have been used in wide range of applications. Several techniques have been devised for building the numerical solutions to perfectly conducting strip gratings and also to penetrable imperfect ones, like resistive and thin dielectric strip gratings the spectral Galerkin moment method 1, the Fourier transformation method 2, the singular integral equation method with projection to orthogonal polynomials 3, and the method of analytical regularization of dual series equations 4.
