Abstract
A magnetic field may be applied to a plasmon path to affect plasmon propagation.
Claims78
A method comprising:
- inducing a surface state at a first location;
- defining a propagation path for the surface state, independently of a separate path-defining structure, by imposing a spatially-varying magnetic field configured to produce a spatially-varying permittivity, the propagation path extending from the first location to a second location spatially separated from the first location;
- and
- selectively controlling propagation of the surface state along the propagation path by selectively controlling the spatially-varying magnetic field.

An apparatus, comprising:
- a first surface state support including an input location and an output location;
- and
- a first magnetically responsive structure interposed at a first central location intermediate the input location and the output location, the first magnetically responsive structure being responsive to a spatially-varying magnetic field to produce a spatially-varying permittivity proximate to the first surface state support to control surface state propagation independently of a separate path-defining structure.

A system, comprising:
- a first plasmon route defining region including a magnetically interactive portion responsive to a first magnetic field to define a propagation route of a first plasmon signal absent a separate routing structure.
