微波频率的表面波在由一对相同的、交替取向的菱形金属管组成的单元格形成的锯齿形超颖表面上被激发。这种特殊的对称性导致衍射激发，具有不同阶的偏振选择性，一个家庭的表面波。此外，在第一布里渊区边界处不存在预期的带隙。
Surface waves at microwave frequencies are excited on a zigzag metasurface formed from unit cells comprised of a pair of identical, alternately oriented, rhombic-shaped metal tubes. This particular symmetry leads to diffractive excitation, with polarization selectivity of different orders, of a family of surface waves. Furthermore, the expected band gap at the first Brillouin zone boundary is absent.
