摘要：

This letter utilizes a simple locally resonant cavity cell (LRCC) model to provide an insight into the physical mechanism and the relationship between locally resonant modes and surface-wave suppression band-gaps of the proposed meandering slotted electromagnetic band-gap (MSEBG) structure. The MSEBG structures have two surface-wave suppression band-gaps that are separately yielded by cross slots and meandering slots. It was proved that the cross slots and the meandering slots produced two different groups of monopolarized ( MP) degenerate modes whose corresponding frequencies located within the two surface-wave suppression band-gaps. The dual-band MSEBG structure was fabricated, and an experimental verification was conducted by surface-wave band-gap measurement using a pair of shield loops. By adjusting the dimension of meandering slot, we can design a dual-band-gap EBG structure effectively.
