Nonlinear Transmission Line Performance as a Combined Pulse Forming Line and High-Power Microwave Source as a Function of Line Impedance

Nonlinear transmission lines (NLTLs) offer compact, low-cost, all solid-state high-power microwave (HPM) generation. This article experimentally investigates the RF output power for composite-based 10, 25, and 50 Ω NLTLs used as a combined pulse forming line HPM source. We manufactured coaxial containing 10% barium strontium titanate 15% nickel zinc ferrite encased in polydimethylsiloxane. The voltage time frequency domains, respectively, showed that 10 NLTL generated greatest output. 25 greater from 500–1100 MHz than NLTL. occurs because reducing impedance induces larger transient current given charging voltage. corresponds to stronger magnetic field, which facilitates moment alignment allow coherent rotation occur. setup eliminates separate network field bias typically other systems, provides additional flexibility tuning device footprint.
