There was some talk of using NLTLs to form impulses suitable for driving signal samplers for such applications as VNAs and TDRs, and I mentioned Holzworth Instruments (Jason Breitbarth) in the "tiny 1200v SiC diode" thread circa 27 April 2026.
There are two critical documents, Breitbarth's PhD 2006 Thesis and a
2017 paper co-written by Breitbarth and his PhD Thesis Director Zoya Popovic, both at the University of Colorado at Aurora CO.
Both documents may obtained gratis from Professor Popovic's publications page:

The PhD thesis leaves a critical detail out, exactly how the needed nearly noiseless control voltage is generated. In 2006, this was a loose end. The answer was published ~10 years later, with Popovic.
