Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are ... En savoir plus

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter ... En savoir plus

Surface Plasmon Resonance (SPR) is created by surface plasmons, coherent electron oscillations existing between any two materials where the real part of the dielectric function changes sign across the interface. SPR technology is based on the electromagnetic field component of incident ... En savoir plus

When electromagnetic waves propagate through matter, they interact with inhomogeneities and particles that can locally disrupt the electron distribution, causing electromagnetic radiation and scattering. One mathematical model used to describe the scattering of electromagnetic waves is ... En savoir plus

The environments in which sensors are most integral are often the most harsh and unforgiving, such as vacuum chambers, the ocean floor, and petroleum reservoirs. Traditional sensing techniques are not ideal in these applications, whereas optical fiber sensors can provide a versatile ... En savoir plus

Engineers at WiTricity have developed a flexible wireless charging setup that relies on magnetic resonance and can be used for a range of applications, including medical implants, electric vehicles, and consumer electronics. Using COMSOL Multiphysics® software, the team analyzed the ... En savoir plus

If electric vehicles are to ultimately transcend from niche to mainstream, their motor designs must continually progress. Modern improvements in electric vehicle motors, known as power magnetic devices (PMDs), come in the form of simultaneous increases in power capability and ... En savoir plus

The chemical reactions used to generate solvents and certain pharmaceuticals rely on organic synthesis, a process of combining individual chemicals that can be accelerated through microwave heating. A microreactor system facilitates the direct, localized, and efficient temperature change ... En savoir plus

For over 50 years, power generation through nuclear fusion has been the focus of international research efforts to demonstrate its use as a clean, safe, and practically limitless source of energy. Researchers at the MIT Plasma Science and Fusion Center (PSFC) proposed the Advanced ... En savoir plus

Dozens of safety features in modern automobiles help reduce risk while driving, but regardless of their complexity, the most important obstacle between passengers and other cars is the frame. Safety standards require certain strengths for car frames, and much of this strength comes from ... En savoir plus
