Features of microwave propagation through a two-dimensional periodic structure of cylindrical spiral coils were studied in the frequency range from 8.5 to 12 GHz. The frequency dependence of the effective refractive index n (ef) of the structure is measured. The features of measurements are noted and the structure reflectance is estimated in various regions of the frequency range under study. In the frequency range where n (ef) similar to 0, a surface wave propagating around the structure is detected.
