“…The unit cell of the proposed tunable triple-band metamaterial is shown in Figure 13(a) [48]. A 0.03-mm-thick copper SLR is printed on one side of a Rogers TMM 4 substrate (ε r = 4.5, loss tangent tan δ = 0.002).…”

In this chapter, we will first present the research progress on the active and tunable meta materials based on different realization methods, such as varactor diodes, liquid crystals, superconductivity, and structural-shifting structures. Then we focus on the achievements in our research group for the tunable metamaterials by using the ferrite as the substrate of metamaterials. We will present the designs and theories of single-, dual-, and tripleband tunable metamaterials based on the ferrite and the design of metamaterial absorb ers based on the ferrite. It will indicate that the proposed tunable metamaterials have many advantages compared with other active and tunable metamaterials.

“…Both cases are consisting of a single closed loop with three order meandering parts. When the electromagnetic waves act on such inclusions along the -axis with the electric field along the -axis, they will show two typical magnetic resonance states and a slight electric resonance state, as shown in Figures 1(b) and 1(e), respectively [13,17]. The surface current distributions at such two magnetic resonance frequencies are shown in Figures 1(c) and 1(f) to indicate resonance characteristics.…”

We systemically analyze and discuss a group of miniaturized triple-band planar monopole antennas by integrating with a single loop resonator (SLR) as part of the radiation patch. Two configurations (rectangular and circular shaped radiation patches) are presented and the corresponding SLRs are integrated in the patches to contribute additional operating frequencies. Two feed techniques (coplanar waveguide and microstrip feeds) are performed to couple the electromagnetic waves. The conventional planar monopole antennas without the SLRs are also analyzed comparatively. Numerical and experimental methods are performed to demonstrate and discuss the proposed designs.

“…The SLR-based MTM have previously been discussed and identified capable of extracting multiband negative permeability [25,27,28]. In this paper, we designed a circular SLR for the purpose of restraining electric coupling in the design of the tunable triple-band LHM.…”

“…We theoretically analyzed the CL-SWPbased MTM. The SLR-based MTM [25,27,28] is also single-sided and is capable of extracting dual-band negative permeability. In our design, we print the circular SLR on the other side of the CL-SWP-based MTM to build a novel LHM.…”

A novel tunable triple-band left-handed metamaterial (LHM) composed of a single-loop resonator (SLR) and a variable capacitorloaded short wire pair (CL-SWP) printed on both sides of a substrate is presented in this paper. The CL-SWP-based metamaterial (MTM) is a novel single-sided LHM. It is theoretically analyzed capable of extracting tunable negative permeability and a wideband negative permittivity. We ran simulations for the CL-SWP-based MTM, the SLR-based MTM, and the proposed LHM. Together with the measured results, it is identified that this novel LHM exhibits a tunable triple-band left-handed (LH) property. With the increase of the loaded capacitance, one LH band is relatively stable, while the other two are moving towards lower frequencies with their bandwidth getting wider and narrower, respectively. The surface current density distributions indicate that the first LH band is mainly decided by the SLR, one of the rest 2 LH bands is mainly decided by the CL-SWP, and the other one is decided by the SLR and CL-SWP together.
