Angela Stelson (Fed)

I develop new microwave measurement techniques for coaxial, waveguide and on-wafer applications. The measurement techniques I develop have applications in fundamental communications technology and support NIST’s traceability in microwave impedance. Additionally, through work in the NIST-on-a-Chip project, I am developing new microwave microfluidic measurements that have applications in medical diagnostics, catalysts and pharmaceuticals.
