NIST PREP Research Scientist in Large Signal Microwave Measurements and Modeling for Advanced Materials

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may want to collaborate with researchers at academic institutions on specific projects of mutual interest and, therefore, requires those institutions to be recipients of a PREP award. The PREP program involves staff from a wide range of backgrounds conducting scientific research across various fields. Individuals in this position will perform technical work supporting the collaboration's scientific research.

Research Title: Large Signal Microwave Measurements and Modeling for Advanced Materials

The work will entail: Associate will work on large signal microwave-frequency electromagnetic measurements and modeling to evaluate the response of advanced materials including magnetic composites Measurements include oscilloscope and vector-network analyzer characterization of advanced materials and devices, including under high-power conditions. Connecting measurements to large-signal models of materials and devices is a key element.

U.S. Citizen Preferred

Key responsibilities will include but are not limited to:

• Perform microwave-frequency measurements using tools including a vector network analyzer and/or oscilloscope coupled with a high-power modulated signal source.
• Perform near-field and/or thermal imaging measurements with experimental setups that include scanning capabilities.
• Perform data analysis, uncertainty analysis, and modeling of material-loaded transmission lines and bulk fixtures.

Qualifications

• Advanced degree or equivalent experience in mechanical engineering, electrical engineering, physics or related field.
• Experience with electromagnetic modeling, including finite element and/or circuit modeling.
• Proficiency with scripting (ex. read files, perform calculations, and plot results) in Python, Matlab, or another scientific programming language.
• Proficiency with the mathematical techniques used in physical sciences and engineering, especially linear algebra, differential equations, and statistics.
• Proficiency with the physical principles of electromagnetism, circuits, heat transport.
• Aptitude for laboratory work, particularly assembling instruments and performing electrical or electromagnetic measurements. This aptitude could be demonstrated through research experience, senior projects, advanced laboratory courses, or hobbies.
