Manipulating chiral transmission by gate geometry: switching in graphene with transmission gaps.
We explore the chiral transmission of electrons across graphene heterojunctions for electronic switching using gate geometry alone. A sequence of gates is used to collimate and orthogonalize the chiral transmission lobes across multiple junctions, resulting in negligible overall current. The resistance of the device is enhanced by several orders of magnitude by biasing the gates into the bipola...
متن کاملBeam manipulating by gate-tunable graphene-based metasurfaces.
We propose an unprecedented transmit-array configuration which can mold the incident beam by modulating phase and amplitude wavefronts. The transmit-array is composed of patterned graphene metasurfaces as shunt admittance sheets. Thanks to the exceptional features of graphene such as tunability, thinness, low loss, and high confinement of graphene plasmons, the proposed subwavelength structure ...

We consider the application of Dantzig-Wolfe decomposition to stochastic integer programming problems arising in the capacity planning of electricity transmission networks that have some switchable transmission elements. The decomposition enables a column-generation algorithm to be applied, which allows the solution of large problem instances. The methodology is illustrated by its application t...

متن کاملTransmission properties in chiral metamaterials
Transmission properties of chiral metamaterials are investigated through the loss factor. Besides the amplitudes of transmission coefficients of right and left circularly polarized waves, the phases are the other main keys to control the refractive index and chirality of the chiral media, directly affecting the loss factor (LF). The LF is low when the phase combination of circular waves is larg...
