A Toroidal Metamaterial Switch. Toroidal dipole is a localized electromagnetic excitation that plays an important role in determining the fundamental properties of matter due to its uniqu... M Gupta,YK Srivastava,R Singh - John Wiley & Sons, Ltd 被引量: 0发表: 2018年 Low-loss and high-Q ...
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 ...
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 (...

Toroidal quantum states are most promising for building quantum computing and information storage devices, as they are insensitive to homogeneous magnetic fields, but interact with charge and spin currents, allowing this moment to be manipulated purely by electrical means. Coupling molecular toroids into...
Optical toroidal dipolar response by an asymmetric double-bar metamaterial We demonstrate that the toroidal dipolar response can be realized in the optical regime by designing a feasible nanostructured metamaterial, comprising asy... ZG Dong,J Zhu,J Rho,... - 《Applied Physics Letters》 被引量: ...

In 1939, R. D. Richtmyer, who studied the resonant properties of dielectric materials in different shapes such as spherical, ring, and toroidal, predicted the concept of generating electromagnetic radiation from such dielectric geometries [13]. Nevertheless, such a concept was unpopular among scientis...
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 ...
