toroidal phase shifterIn this paper, the design of a rectangular waveguide metamaterial (MTM) phase shifter will be introduced in X band. The main disadvantages of the class of waveguide MTM phase shifters include high insertion loss (about 10 dB) and high DC magnetic bias field requirement (...

We present a controllable terahertz (THz) metamaterial switch by manipulating toroidal dipolar mode in simulation. The metamaterial switch consists of periodically patterned metallic split rings with photosensitive silicon stripes. The excitation of toroidal dipolar resonance is closely dependent on the ...
In general, the addition of an immiscible solvent (also known as a bad solvent) to a colloidal NP solution can trigger SA of the NPs, as the immiscible solvent causes the surface ligand molecules to switch between stabilized and destabilized states. This process reduces the steric repulsion ...

A tunable planar metamaterial with a high contribution of the toroidal dipole moment in the microwave range is theoretically and experimentally studied. The properties of such a structure are controlled by switching on a PiN diode. It is demonstrated that the metamaterial can be transparent or ...
toroidal dipole excitationThis cover image shows the reconfigurable terahertz metamaterials where artificial toroidal metamolecules and traditional MEMS bi-material cantilever structures are integrated within the same unit cell. This enables enhancement of the toroidal dipole response through reorientation of ...
Toroidal excitations are a class of electromagnetic excitations that take place when magnetic moments develop an end-to-end formation. The toroidal excitation has the advantage of lower radiative losses. One unique way of decreasing linewidth of resonances is to couple the MM resonance to the first...
Here, we demonstrate a toroidal moment of Berry curvature with flux approaching to 蟺 in judiciously engineered metamaterials. The Berry curvature exhibits a vortex-like configuration without any source and drain in the momentum space. Experimentally, the presence of Berry curvature toroid is confirmed...
In this work, a dipolar toroidal response is demonstrated by a plasmonic metamaterial composed of a ring and a disk. We theoretically demonstrate that the toroidal dipole can couple with the magnetic dipolar response (subradiant mode) and thus induce the EIT-like phenomenon by breaking the ...
