A superconductor device includes a high superconductivity transition temperature enhanced from the raw material transition temperature. The superconductor device includes a matrix material and a core material. The enhancing matrix material and the core material together create a system of strongly coupled carriers. A plurality of low-dimensional conductive features can be embedded in the matrix. The low-dimensional conductive features (e.g., nanowires or nanoparticles) can be conductors or superconductors. An interaction between electrons of the low-dimensional conductive features and the enhancing matrix material can promote excitations that increase a superconductivity transition temperature of the superconductor device.

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.

Electromagnetic cloaking method

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.

An automatically adjustable radiofrequency link system includes a radiofrequency transmitter configured to transmit a signal at a frequency of transmission within an extremely high frequency (EHF) band. The system further includes a receiving device configured to receive the transmitted signal and provide feedback to a processing circuit communicatively coupled to the transmitter and the receiving device, wherein the feedback is related to the received signal. The processing circuit is configured to determine required signal properties based on the feedback and determine signal loss properties including an effect of atmospheric absorption, as a function of frequency; determine a modification to the transmitted signal using the signal loss properties and the required signal properties; and adjust the frequency of transmission to obtain a desired transmission signal using the modification.

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.

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.

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.
