Decomposition of a UWB Pulse in Structures with Facial Feedback

Abstract

The urgency of protection of radio-electronic equipment from UWB pulses is indicated. The principle of modal filtration based on the application of the physical phenomenon of signal decomposition in transmission lines is shortly described. An asymmetric modal filter with facial feedback is analyzed. Its models with different parameters have been developed and manufactured. A field experiment and a computer simulation of the time response to a 1 ns pulse width have been performed. The agreement between the experimental and simulation results is demonstrated. For a modal filter with optimal parameters, the input pulse attenuation by 5 times is demonstrated in a 50-Ω channel.
