Metamaterials

Description of past research & capabilities for Metamaterials: 

The field of Metamaterials includes the research and development of numerous types of structures that exhibit optical, acoustical and mechanical properties not found in nature.  In particular, optical metamaterials include research fields of photonic crystals and plasmonic crystals besides the more traditional types of metamaterials (e.g., split-ring resonator arrays, negative index of refraction materials…).  There are a number of laboratories at CUNY that perform basic and applied research on these types of structures including:

Professor David Crouse and the CUNY Metamaterials Laboratory with over nine different projects on developing metamaterials for renewable energy devices, sensors and optical components.  Funding for the projects comes from numerous government agencies (e.g., DARPA, MDA, NSF, DOD, NASA) and industry.  A large emphasis is placed on applied research and development.  Approximately half of the lab’s projects are funded by industry with the goal of transitioning the technology to industry.  Professor Crouse is also the PI for the NSF-funded Center of Metamaterials that is being established in Spring 2011.

Research/Expertise in Metamaterials

Professor Crouse and the Metamaterials Research Laboratory has over 15 years of experience in metamaterials, 25 publications on metamaterials, numerous current projects on metamaterials for renewable energy devices, sensors and optical components.  The range of research spans theoretical research (e.g., discovering new optical effects within metamaterials, development of more efficient and accurate modeling methods…) to applied research, engineering and development of solar cells, polarimetric focal plane arrays, actively configurable apertures.

Research being performed in his laboratory include:

  • Modeling photonic crystals, plasmonic crystals and metamaterials using Ansoft HFSS, Sonnet Software’s CST, COMSOL, and proprietary rigorous coupled wave algorithms
