What are Metamaterials A State of the Art Review of Smart Materials A Review of Metamaterials in the UK December 2015 Metamaterials are engineered to exhibit unique electromagnetic and acoustics properties. Metamaterial designs enable devices that achieve much higher performance and efficiency than conventional offerings Artificial functional composite materials A State of the Art Review of Smart Materials A Review of Metamaterials in the UK December 2015
Examples of targeted applications: • 5G networks • Autonomous and connected vehicles • Telecommunication antennas • Electromagnetic sensors like radar and lidar • Managing sound • Vibration damping • Energy harvesting • Wireless charging Metamaterials To grow to $10.7 billion globally by 2030 (Pre-Covid 19)
Metamaterials Barriers to commercialisation • These materials are not easy to understand • Require sizeable resources to deliver useful products • Require skills and expertise that are difficult to find • Require to be part of resilient supply chains • Fundamental R&D is still needed but there exists a large portfolio of R&D outputs to translate the research into timely products and services UK has excellent academic research in this field but lacks industrial uptake from non-defence sectors
Metamaterials Innovation Network This is a 2-year project run by KTN and supported by Innovate UK to ensure successful commercial exploitation and technology transfer of metamaterials through brokered or encouraged collaboration Objectives: 1. identify and exploit commercial opportunities for metamaterials 2. build metamaterials innovation community to promote knowledge and technology transfer 3. engage product design, manufacturing technologies, investors and end-users 4. build valuable collaborations to develop metamaterials applications 5. engage investors to help deliver new metamaterials-based products

Return on investment: falling behind the curve? The US national advanced manufacturing community, MForesight, highlighted actions necessary to ensure that metamaterials become more broadly adopted to address practical applications and deliver societal and economic value. The Chinese government has funded the development of the world’s first large-scale metamaterial fabrication facility, which has capacity to produce 100,000 m2 of metamaterial plates annually, with projects relating to aerospace, communication, satellite and military applications. The UK’s Advanced Materials Leadership Council (AMLC) recognised the strengths of UK-based research, but highlighted that in metamaterials in general “the UK is lagging the USA and South East Asia”.

MRI Metasurface to Enhance SNR
September 23, 2020 22 Problem MRI may be considered the safest and most informative method of examination of internal organs of humans however it is capital intensive and scan time can be very long with some exams lasting as long as 1 hour this: • Limits the accessibility to MRI services to patients in capital restrained public health systems • Limits the ROI of assets in private health systems • Provides for a poor patient experience as MRI scanners are claustrophobic and noisy MRI is a capital intensive diagnostic imaging tool of which scans take a long time therefore limiting patient access to services and provider’s ROI on assets In the NHS (UK) • 158k people were waiting for an MRI scan • 20% increase in 12 months • 2.4m MRI tests were carried out in the last 12 months • 13% increase on prior year Source: NHS Waiting Time & Activity Report Feb 2014
September 23, 2020 23 The “MagneWise” solution MagneWise is a unique and proprietary invention that has potential to increase the productivity of an MRI suite by at least 25% • Increase signal to noise ratio (SNR), a key metric that determines the quality and/or duration of an MRI scanner by 2-3X • Estimate that it will halve scan time making MRI suites 25% more productive* • Pad that is placed next to the patient in existing or new MRI scanners • Currently tested in 1.5T MRI scanner, can also be developed for 3.0 and 7.0 scanners to advance research • Imminent patent application for metamaterial technology with high confidence of success in protection • Passive device that is expected to be a Class I device for regulatory approval * Assuming scan time represents 50% of a patient appointment
