I'm looking to write a story for one of eeweb's sister publications about some unusual applications for vector network analyzers (VNAs). That is, measurements outside the usual characterizing connectors, cable, PCB traces, filters, etc. For example, medical measurements, food, tank levels, finding cracks in materials, material characterization, and so on. If you've ever used a VNA outside it's usual intended measurements, please contact me at martin [dot] rowe {at} aspencore.com or call my office at +1-718-360-2348.Thanks
