Analysis and Design of Switched Transmission Line Circuits for High-power Wide-band Radiation

High Power Wide-Band (HPWB) radiators have been studied for a number of applications such as electromagnetic car stopper. Switched Transmission Line Circuit (STLC) is widely used as Ultra Wide-Band (UWB) and Wide-Band (WB) pulse generator in HPWB radiator. Since performance of the STLC depends on methods to connect switch to transmission line, in a stage of conceptual design we qualitatively determine a method of connection with respect of increasing amplitude of radiated electric fields and energy efficiency. We present circuit analysis for the STLC built by this method. The results of analysis are useful for understanding and designing HPWB radiators using the STLC. A couple of HPWB radiators based on this approach are introduced as examples.
