摘要

摘要提出并研究了一种产生纳秒长度和皮秒上升时间的超宽带电磁脉冲的方法。该方法使用一个带有光电导开关的喇叭天线作为发射器，通过激光脉冲进行照射。研究表明，超宽带电磁脉冲的长度由天线长度和半导体材料决定，而上升前沿则由用于启动光电导开关的激光脉冲前沿决定。据报告，典型的脉冲长度为 ~1 ns，上升前沿可达 ~34 ps。

Generation of Rectangular Nanosecond Electromagnetic Pulses with a Picosecond Rise Front

Abstract

A method for generation of ultra-wideband electromagnetic pulses with a nanosecond length and a picosecond rise time has been proposed and studied. A horn antenna with a photoconductive switch irradiated by laser pulses has been used as an emitter. It is shown that the length of ultra-wideband electromagnetic pulses is determined by the antenna length and the semiconductor material and the rise front is determined by the front of laser pulses used to initiate a photoconductive switch. Typical pulse lengths of ~1 ns with a rise front of up to ~34 ps are reported.
