Engineered Electromagnetic Surfaces (EES)

The ability to control the EM propagation environment is an important area of 6G research. Applications such as reconfigurable intelligent surfaces (RIS) rely on either metasurfaces or reflect arrays, an alternative technology, to optimize wireless channels.

Engineered electromagnetic surfaces (EES) are a class of passive metasurfaces that artificially enhance wireless coverage at microwave and millimeter-wave frequencies via printed conductive patterns on substrates such as plastic or glass. When placed on a wall, window, or other structure, the scattering properties of these printed patterns redirect RF wave propagation in specific directions to augment wireless connectivity. Wireless InSite’s EES capability provides a way to analyze improvements to coverage from either a static EES or a single configuration of a metasurface-based RIS.

Wireless InSite’s EES capability is based on the Ray-Optical EES Scattering model developed by the Communications Research Centre Canada (CRC), part of Innovation, Science and Economic Development Canada. The implementation of the model within Wireless InSite’s ray-tracing and EM path processing calculations enables the prediction of reflections, transmissions, and diffractions that interact with EES placed within office buildings and urban areas.
