Electromagnetic wave diffraction by the microstrip two-periodic grating of chiral metal strips

Reflection characteristics of microstrip two-periodic gratings of perfectly conducting infinitely long strips having the complex shape are considered. The effect when reflected field possess orthogonal polarization relative to incidence wave polarization is considered. The possibility of insertion the control device in strips for the transformation considered grating to the array from the strip disconnected elements is proposed. The possibility for the structure application as high-impedance surface is considered. The comparison of the reflection properties of the two-periodic gratings of non-chiral strips and straight-line strip gratings is presented.
