Abstract

The Blumlein transmission line (BTL) has broad applications in pulse modulation, microwave technology and pulsed power technology. In this paper, a new theoretical method for variable reflection and transmission of electromagnetic waves at the inductive port of transmission line is put forward, in order to analyze the wave reflection characteristics of BTL at the inductive port formed by a saturated magnetic switch. At the inductive port, the variable reflection and transmission mechanisms of the voltage waves traveling through the BTL are analyzed in detail, and the inductive effects on the square voltage pulse of load formed by the BTL are also studied. Simulation and experimental results both demonstrated the proposed new theoretical method which shows great value on high-power microwave technology, high-power pulse forming, pulse shaping and modulation.
