Jim Booth (Fed)

Guided Wave Electromagnetics Group Leader

A physicist at the National Institute of Standards and Technology (NIST) in Boulder, CO since 1996, originally as an NRC postdoctoral research associate (1996-1998) and currently as Leader of the Guided Wave Electromagnetics Group within the Communications Technology Laboratory. His research at NIST is focused on quantifying electromagnetic interactions in new electronic materials and devices, including piezoelectric, ferrite, magneto-electric and superconducting materials, as well as linear and nonlinear measurements and modeling of signal control components such as transmission lines and filters.

Dr. Booth is a member of the American Association for the Advancement of Science (AAAS) and is active on two technical committees of the IEEE Microwave Theory and Techniques Society, including Biological Effects and Medical Applications of RF and Microwaves, and Microwave Superconductivity.


Dr. Booth was the recipient of a Department of Commerce Bronze Medal in 2015 for the development and application of measurements to determine electrical properties of thin-film materials over a range of frequencies from a few hertz to the terahertz regime.
