The objective of the UK Foresight Project entitled EEMS – ‘Exploiting the Electro-Magnetic Spectrum’ was to provide a vision for the future exploitation of the electromagnetic spectrum to ensure increased UK innovation in related areas. Technologies that ‘exploit’ the Electro-Magnetic Spectrum include lasers, X-rays and other medical technologies as well as technologies for communication, the miniaturization of complex micro-systems, sensing, imaging as well as security.
