“…In fact, the dual‐band nature of this structure is caused by the two pairs of split rings with different twist angles. This method is known as combined elements method, which is widely used in designing dual‐band (or multiband) frequency selective surfaces and traditional MMs . The linewidth of the ring is 0.5 mm and the inner radius is 3.5 mm.…”

A dual‐band planar chiral metamaterial (CMM) with strong optical activity is experimentally constructed by twisted split rings. Resonant frequencies with strong optical activity are around 7.9 and 8.9 GHz for right circularly polarized (RCP) and 9.95 and 10.9 GHz for left circularly polarized (LCP) wave, respectively. In particular, the two independent eigenfrequencies depend sensitively on the twist angles, which can offer a convenient approach in building multiband or tunable CMMs. With the twist angle increased from 0° to 90°, the resonant frequencies play an obvious blueshift for RCP wave and redshift for LCP wave, respectively. Current distributions are also studied, which demonstrate that the observed resonances are linked to the excitation of multimodal standing current waves. Microwave experiments are performed to successfully realize these ideas and results are in good agreement with the numerical results. © 2014 Wiley Periodicals, Inc.

“…So arranging some different elements that have obviously different resonance frequencies and shapes in a periodic cell will present a dual‐band or further multiband response. This method can be named as combined element method that has been applied for a long time in designing frequency selective surface [22, 23] and our structure can be called combined element LHM. However, it is difficult to tune the size for planar LHM because not only the electric response but also the magnetic response should be coupled carefully above multibands to achieve negative refractive index $n = \sqrt {\varepsilon (\omega )\mu (\omega )} $ .…”

We report on a new kind of planar left‐handed metamaterial with both simulations and experiments in this article. Dual electric and magnetic resonance frequency bands are experimentally realized by introducing two different metallic elements in one unit cell, which offers a convenient approach in building dual‐band or multiband negative‐index metamaterials. The effective electromagnetic parameters obtained from the measured S‐parameters indicate that negative refractive indexes are verified near 8.5 and 12 GHz with both negative permittivity and negative permeability. Field and current distribution at the dual resonances are also examined. At last, we calculated the radiated power of the magnetic dipole moments along y‐axis. The idea can help us to fabricate dual‐band or multiband metamaterial absorbers, filters, and antennas. © 2012 Wiley Periodicals, Inc.

“…With the increasing requirements of multifrequency communications, multiband and dual-polarization FSSs have aroused great interest of many researchers. Different design methods of multiband FSS can be found in many papers, which include single screen FSS with combined element method [2], multi-screen FSS cascaded method [3], genetic algorithm [4], fractal FSS [5], or several combination of above methods [6].…”

A novel dual-band miniaturized frequency selective surface adopting fractal elements is proposed. The proposed structure is composed of interconnected four SZ curves of second generation. Such a design is to provide two pass-bands with stable performance, the first band resonates at S-band with a center frequency of 3.02 GHz and the second band is at C-band centered at 7.22 GHz. In addition, the compact structure employing the space filling curve can further reduce the size of the FSS. The dual-band FSS achieves better miniaturization compared with other single layer FSS in previous literature, the dimension of the unit cell is only 0.072λ × 0.072λ, where λ represents the free space wavelength at first resonant frequency. Furthermore, the proposed FSS exhibits great resonance stability for different polarizations and incidence angles. Both the simulation and measurement verify the stable performance of the FSS.
