Abstract

A narrowly directed wavebeam injected into an oversized rectangular waveguide can bepresented as a sum of eigenwaves. Each of them is transmitted to the remote cross-section,where they form an image of the initial wavebeam. There are certain distances, where theinitial profile is repeated or split into a few beams with their amplitude profiles identical tothe initial one [11. Any initial profile is repeated at the distance i.----8a2,7,15 where a is widthof the waveguide., X is wavelength. The symmetrical profile is repeated at L i=a2/it, and splitinto n beams at Ln=a2/n2 (Fig. 1). Non-symmetrical input of a wavebeam results insplitting of the initial wavebeam into non-equal parts (Fig. 2). Similar effects can beformulated for linear-sectorial waveguides (Fig. 4).
