Postdoctoral Fellow; PREP

General Description

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.

0004208 - 672.03 - OTA Communications Measurements with Traceable Signal and Channel at mmWave Frequencies

The RF Technology Division of the Communications Technology Laboratory at NIST is seeking a qualified candidate for a postdoctoral position working with traceable measurement systems for wide bandwidth modulated signals. The candidate will set up and automate hybrid anechoic measurements. The candidate will work with synthetic aperture techniques and make them traceable to primary standards to characterize over-the-air communications channels. The candidate will also use a precision modulated signal source and signal processing to incorporate low-distortion communications signals into the setup to create a unique test environment for novel 5G and 6G systems incorporating beam‑steering phased arrays.

The candidate will incorporate measurement uncertainties into the analysis using the NIST Microwave Uncertainty Framework.

U.S. Citizen Preferred

• Precision electromagnetic field measurements and uncertainty evaluation.
• Development of multiport OTA measurement approaches, including assessment of measurement uncertainty.
• Instrument automation.
• Accurate modulated‑signal analysis of signals.
• Analysis of data and measurements to provide a complete traceability path to primary standards.
• Experimental design to create repeatable test conditions that best expose devices to a traceably known condition.
• Present and publish technical results.

• Ph.D. in Electrical Engineering, Physics, or related field.
• Research experience involving one or more of the following areas: RF measurement, antenna design/characterization, signal processing, EMI/EMC testing.
• RF measurement experience.
• Antenna design/characterization.
• Signal processing.
• Experience with microwave electronics simulation software (e.g., HFSS and ADS) is desirable.
• Experience with Lab View, MATLAB, Python, other measurement automation and analysis software.
• Mechanical and electrical design and fabrication capability is desirable.
• Metrology and uncertainty analysis experience.
