关于客户
The Center for Metamaterials and Integrated Plasmonics (CMIP) at Duke University, led by David R. Smith, is a leading research organization in the field of metamaterials. CMIP is known for its work on electromagnetic cloaking and is also involved in developing magnetic metamaterials for wireless power transfer for electric vehicles in collaboration with Toyota Corporation. Another key player is the Naval Postgraduate School (NPS) in Monterey, California, where researchers like Fabio Alves are developing metafilms for less expensive terahertz (THz) imaging devices. These organizations are at the forefront of metamaterials research, pushing the boundaries of what is possible with these advanced materials.
挑战
Metamaterials, which are artificially structured materials, have the potential to revolutionize various fields by manipulating electromagnetic waves. However, the challenge lies in the high level of control required over their structure and the high ohmic loss due to the metal components. These materials derive their unique properties from their structure rather than their chemical composition, making the design and fabrication of complex structures a significant challenge. Additionally, precise knowledge of the response at each frequency of interest is needed, making accurate frequency-domain simulations a requirement. The high ohmic loss causes electromagnetic waves to be strongly attenuated, posing another challenge in the practical application of metamaterials.
解决方案
To address the challenges in designing and fabricating metamaterials, researchers are leveraging advanced modeling and simulation tools like COMSOL Multiphysics. These tools allow for precise frequency-domain simulations, which are crucial for understanding the electromagnetic response of complex structures. The flexibility and versatility of these tools enable researchers to modify boundary conditions and even change the equations themselves, providing a high level of control over the design process. For instance, the Naval Postgraduate School is using these tools to develop metafilms that exhibit near 100 percent absorption in the desired frequency, significantly improving the efficiency of THz imaging systems. Similarly, the Center for Metamaterials and Integrated Plasmonics at Duke University is using these tools to develop metamaterial-based lenses for wireless power transfer, making the distance between the power source and the device being charged appear to disappear.

Case Study
Hospital Inventory Management
The hospital supply chain team is responsible for ensuring that the right medical supplies are readily available to clinicians when and where needed, and to do so in the most efficient manner possible. However, many of the systems and processes in use at the cancer center for supply chain management were not best suited to support these goals. Barcoding technology, a commonly used method for inventory management of medical supplies, is labor intensive, time consuming, does not provide real-time visibility into inventory levels and can be prone to error. Consequently, the lack of accurate and real-time visibility into inventory levels across multiple supply rooms in multiple hospital facilities creates additional inefficiency in the system causing over-ordering, hoarding, and wasted supplies. Other sources of waste and cost were also identified as candidates for improvement. Existing systems and processes did not provide adequate security for high-cost inventory within the hospital, which was another driver of cost. A lack of visibility into expiration dates for supplies resulted in supplies being wasted due to past expiry dates. Storage of supplies was also a key consideration given the location of the cancer center’s facilities in a dense urban setting, where space is always at a premium. In order to address the challenges outlined above, the hospital sought a solution that would provide real-time inventory information with high levels of accuracy, reduce the level of manual effort required and enable data driven decision making to ensure that the right supplies were readily available to clinicians in the right location at the right time.
