Job description

PREP Research Associate

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). 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

PREP0004208 - 672.03 - OTA Communications Measurements with Traceable Signal and Channel at mmWave Frequencies

Work will entail

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, work with synthetic aperture techniques and make them traceable to primary standards to characterize over‑air communications channels, incorporate a precision modulated signal source and signal processing to create a unique test environment for novel 5G and 6G systems incorporating beam‑steering phased arrays, and use the NIST Microwave Uncertainty Framework to incorporate measurement uncertainties into the analysis.

Key Responsibilities

• 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 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

Qualifications

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