A 2D array of unit cells, each with electromagnetically coupled resonators, enables independent control of reflection phase and magnitude at specified frequencies.
About
To support the increased demand in data capacity for 5G and beyond wireless networks, current efforts are focused on migrating towards higher frequency bands, including millimeter-waves (typically 24 GHz onwards). Near-directive 5G communications can exploit the paradigm shifting concept of engineering the radio environment to consciously manipulate and distribute the EM power to desired destinations. To this end, Carleton’s Metamaterial Smart Reflector can be installed in strategic areas of a given radio environment (e.g., ceilings, floors and other objects) and, in co-operation with fixed antenna sources and receivers, guide the EM power along preferred directions.
Carleton researchers have developed and tested a novel metasurface that provides unprecedented control of the reflection characteristics of the surface. The architecture consists of a 2D array of unit cells each comprising electro-magnetically coupled resonators. This novel unit cell configuration enables independent control of reflection phase and magnitude at the specified frequency, resulting in a smart software programmable reflector system scalable to various frequency bands.
