電磁波的起伏傳播
UNDULATING PROPAGATION OF THE ELECTROMAGNETIC WAVE
-
摘要: 本文提出了電磁波傳播的起伏傳播方式概念及其由具有時變初旋轉(zhuǎn)相位角的多頻圓極化輻射源形成的起伏傳播的工作原理,并介紹了起伏傳播的一些特點.這種新傳播方式異于我們過去熟悉的均勻傳播方式的最大特點是沿途電磁波分布的起伏變化,而這一特點將使得起伏傳播在諸如定點通訊、探測、微波送電等許多傳統(tǒng)的電磁波應(yīng)用方面獲得應(yīng)用.

Abstract: The idea about undulating propagation of electromagnetic wave is presented. And some characters and operating principle to form undulating propagation of electromagnetic wave by multifrequency radiation source with initial twisty phase angle continually varying versus the time are introduced. The electromagnetic wave propagation in the undulating pattern along the propagating path will profit many fields of the electromagnetic wave application, such as point to point communication, electromagnetic energy conveyance,detection and ranging etc. -
