Electromagnetic Wave Diffraction by Planar Doubly-Periodic Grating of Wavy-Shaped Crossed Metal Strips

Reflection and transmission properties of planar doubly-periodic gratings of perfectly conducting infinitely long crossed wavy-shaped strips are considered. The diffraction characteristics; of-the gratings were calculated by using the method of moments. The possibility of the using of the control, electron devices is discussed to transform the grating of uninterrupted strips into array of separate gammadion-shaped particles. The comparison of the reflection properties of the doubly-periodic gratings of infinity long crossed strips and gammadion-shaped strip particles is presented
