ABSTRACT

The decomposition method is employed to solve the spectral problem on propagation constants of TM-modes of the periodic waveguide produced by a rectangular-groove reflecting grating filled with metamaterial of negative permittivity. The characteristic behavior of the eigenwave dispersion dependences is theoretically studied through a wide range of waveguide parameters. It has been found that Bragg regimes may appear by varying the grating geometric parameters and metamaterial characteristic frequency.
