Abstract

The problem of reflection of a normally incident electromagnetic wave from a periodic structure of conducting grids with square cells, placed into a dielectric layer lying on a metallic mirror, is solved. It is shown that, with an appropriate choice of parameters, this structure can be low-reflecting in a wide frequency range. It is established that, if the grids are sufficiently fine, such a structure has a frequency-dependent reflection coefficient, which is similar to a structure with conducting films instead of the grids. The results of the work can be used to create low-reflection coatings used for various purposes in microwave technology.
