Various methods for sensing and/or heating that utilize nanostructures or carbon structures, such as nanotubes, nanotube meshes, or graphene sheets, are disclosed. In some methods, at least a pair of contacts are electrically coupled with a given nanostructure or carbon structure to sense a change or to pass a current for heating.

Systems and methods for selective sensing and selective thermal heating using nanostructures

Various sensors and arrays of sensors that utilize nanostructures or carbon structures, such as nanotubes, nanotube meshes, or graphene sheets, are disclosed. In some arrangements, at least a pair of contacts are electrically coupled with a given nanostructure or carbon structure to sense a change.

A method of constructing a concealing volume comprises constructing a plurality of concealing volume elements around a concealable volume. Each concealing volume element has a material parameter arranged to direct a propagating wave around the concealable volume. The material parameter can be refractive index, electrical permittivity, and magnetic permittivity. The concealing volume can be a metamaterial. The concealing volume diverts incoming propagating waves such that outgoing propagating waves appear to be unperturbed to an observer.

Various heaters and arrays of heaters that utilize nanostructures or carbon structures, such as nanotubes, nanotube meshes, or graphene sheets, are disclosed. In various arrangements, at least a pair of contacts are electrically coupled with a given nanostructure or carbon structure to pass a current for heating.

A method of pumping an optical resonator includes directing light generated by a pumping light at the optical resonator, exciting a propagating surface state of the optical resonator at an interface of the optical resonator, and changing a propagating frequency of the light proximate the interface, where the changed frequency corresponds to a propagation frequency of the surface state. The optical resonator includes a photonic crystal and a material, where the interface is formed between the photonic crystal and the material.

A digital memory device includes a moveable element that is configured to move between a first stable position and a second stable position, where the moveable element comprises a first conducting area. The digital memory device further includes a second conducting area on the surface of a substrate. At the first stable position of the moveable element, a first gap exists between the first conducting area and the second conducting area. At the second stable position of the moveable element, a second gap that is smaller than the first gap exists between the first conducting area and the second conducting area. In at least the second stable position, an attractive Casimir force between the moveable element and the substrate holds the moveable element in the stable position.

An apparatus to modify an incident free space electromagnetic wave includes a block of an artificially structured material having an adjustable spatial distribution of electromagnetic parameters (e.g., &#x2208;, &#x3bc;, &#x3b7;, &#x3c3;, and n). A controller applies control signals to dynamically adjust the spatial distribution of electromagnetic parameters in the material to introduce a time-varying path delay d (t) in the modified electromagnetic wave relative to the incident electromagnetic wave.

An apparatus to modify an incident free space electromagnetic wave includes a block of an artificially structured material having an adjustable spatial distribution of electromagnetic parameters (e.g., &#x3b5;, &#x3bc;, &#x3b7;, &#x3c3;, and n). A controller applies control signals to dynamically adjust the spatial distribution of electromagnetic parameters in the material to introduce a time-varying path delay d(t) in the modified electromagnetic wave relative to the incident electromagnetic wave.

Apparatus, methods, and systems provide conversion of evanescent electromagnetic waves to non-evanescent electromagnetic waves and/or conversion of non-evanescent electromagnetic waves to evanescent electromagnetic waves. In some approaches the conversion includes propagation of electromagnetic waves within an indefinite electromagnetic medium, and the indefinite medium may include an artificially-structured material such as a layered structure or other metamaterial.
