Toward band-stop all-dielectric metamaterial frequency selective surface via dielectric ceramic blocks

In this paper, we design a band-stop all-dielectric metamaterial frequency selective surface (FSS) using dielectric ceramics. Four rectangular ceramic blocks, which possess high permittivity and low dielectric loss, can be spliced together to make the designed shapes. The design is based on effective medium theory and dielectric resonator theory. The band-stop response can be determined by the permittivity of the dielectric material, the periodicity and geometrical shape of the dielectric unit cell. The simulation results show that the FSS can achieve a stop band in 6.97–8.85GHz. Due to the utilizing of high-permittivity ceramics, this all-dielectric FSS have potential engineering application in high-temperature and high-power environments and also can be applied to other frequencies.
