Challenge	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. Read More
