A device that produces spin waves includes a base substrate, a transducer that includes a first plane defined by a first magnetic film and a second plane defined by a plurality of metal strips, and a second magnetic film having a spin-wave phase velocity lower than the first magnetic film. The second magnetic film is adjacent to the first magnetic film, and the first plane and the second plane are parallel. The plurality of metal strips are configured to receive a first signal, such that the first signal excites a first spin wave in the first magnetic film. The second magnetic film is configured to produce a second spin wave having a wavelength shorter than the first spin wave.

Short-wavelength spin wave transducer

An example device includes a magnetic film, two or more spin wave generators, and one or more detectors. The magnetic film is capable of supporting spin waves. The two or more spin wave generators are operable to create a diffraction pattern of the spin waves in the magnetic film. The two or more spin wave generators generate the spin waves based on a source signal. The one or more detectors are operable to measure an amplitude of the spin waves in the diffraction pattern. The amplitude measured by a particular detector is indicative of a property of the source signal.

Methods and apparatus for spin wave-based spectrum analyzers

A quilt packaging system includes a first and second electronic device each comprising a plurality of edge surfaces at least a first edge surface of which comprises one or more interconnect modules disposed thereon. The first edge surface of the second electronic device is positioned contiguous to the first edge surface of the first electronic device, and at least one of the one or more interconnect nodules disposed on the first edge surface of the first electronic device is configured to be in physical contact with at least one of the one or more interconnect nodules disposed on the first edge surface of second electronic device so as to provide an electrical connection between the first and second electronic devices at the first edge surfaces of the first and second electronic device.

Systems and methods for inter-chip communication

Nanoscale thermocouples are made of a single material and are shape-engineered to contain one or more variations in their width along their length. The mono-metallic nanowire junctions resulting from the width variation(s) exploit a difference in the Seebeck coefficient that is present at these size scales. Such devices have a wide variety of uses and can be coupled with an antenna in order to serve as an infrared detector.

Mono-metallic thermocouples

The present invention provides a quilt packaging system for microchip, a method for making such a quilt packaging system, microchips that may be used in a such a quilt packaging system, and methods for making such microchips.

Inter-chip communication

A non-majority magnetic logic gate device for use in constructing compact and power efficient logical magnetic arrays is presented. The non-majority magnetic logic gate device includes a substrate, symmetrically aligned magnetic islands (SAMIs), at least one misaligned magnetic island (MAMI), magnetic field inputs (MFIs), and at least one magnetic field output (MFO). The SAMIs and MAMI are electrically isolated from each other but are magnetically coupled to one another through their respective magnetic fringe fields. The MAMI is geometrically and/or angularly configured to exhibit a magnetization ground state bias which is dependent upon which direction the applied magnetic clock field is swept. Non-majority logic gates can be made from layouts containing the SAMIs and the MAMI which contain a smaller number of components as comparable majority logic gate layouts.
