Creating a brighter, faster and more portable future
Electromagnetic fields are all around us. Every time we switch on a light or press a key on our computer keyboard, these fields transmit information to communicate the desired outcome. Light is also anÌýelectromagnetic wave.ÌýElectromagnetics play a significant role in contributing to the development of many new technologies.
From high-speed internet connections and more secure communication to night vision goggles and virtual reality – electromagnetics is changing the world as we know it. The next generation of sensors, wireless communications, imaging, and computing systems will be based on the sophisticated manipulation of acoustic and electromagnetic fields at the smallest scale. This technology presents exciting opportunities and enormous potential for future discoveries, which will enable smart, highly efficient devices with new functionalities.

Impact
Combining nanophotonics, metamaterials, and quantum optics, Advanced Electromagnetic research at ¶¶Òõ¶ÌÊÓƵ looks at acoustic and electromagnetic wave propagation, manipulation, and application to drive future innovations across energy and the environment, health and medicine, communications, computing and security.Ìý
- Nanophotonic research examines the science and application of light at the nanoscale. At such a small scale, the light and matter interaction can beÌýsignificantly enhanced allowing for new applications that differÌýfrom those we are familiar with on an everyday scale. Using nanophotonics we can create new structures to manipulate light at a more precise level. ÌýÌý
Ìý - Metamaterials are artificially structured materials that exhibit electromagnetic properties not seen, or available in nature. They are created on a small scale to manipulate or alter incoming waves like light or sound, causing them to behave in an unusual way.Ìý
Ìý - Quantum optics looks at the interaction of photons, the smallest particles of light, with matter at submicroscopic levels. The study of how photons interact with matter is crucial inÌýunderstanding and revealing the hidden properties of light particles for entanglement, teleportation, and secure quantum information processing.ÌýÌý
