Abstract :
A FSS (Frequency Selective Surface) is composed of metal patches arranged in narrow intervals, and has frequency-band-rejection and frequency-band-pass characteristics. It is known that the FSS with the ground plane has PMC (Perfect Magnetic Conductor) characteristics in a specific frequency band. The surface is referred to as a meta-surface and it can control the phase of the wave which is reflected at the surface. This paper proposes a design method to realize a low-profile meta-surface. In the proposed method, the FSS which has low-pass or high-pass filtering characteristics is utilized. The effects of the filtering characteristics of a FSS on PMC characteristics of a meta-surface are described. Based on the calculated results, it is confirmed that the meta-surface can be obtained by using the FSS. In addition, it is found that the thinner and more wideband meta-surface can be achieved by using the FSS which has low-pass filtering characteristics.
