Abstract

L'invention concerne un guide d'onde comprenant deux parois, dites parois (21) de guidage, chaque paroi (21) de guidage forme : - au moins deux surfaces, dites surfaces (80) multimodes : ○ s'étendant selon ledit axe de propagation dans un plan, dit plan multimode, o une surface multimode étant espacées d'une surface multimode de l'autre paroi de guidage d'une distance de valeur a, - au moins une autre surface, dite surface (81) d'adaptation : ○ s'étendant selon ledit axe de propagation dans un plan, dit plan d'adaptation, entre les plans multimodes des parois de guidage, ○ disposée entre deux surfaces multimodes d'une même paroi, une surface d'adaptation d'une paroi de guidage étant espacé d'une surface d'adaptation de l'autre paroi de guidage d'une distance de valeur b, a et b étant choisies pour permettre la propagation simultanée et sélective de deux modes de propagation orthogonaux.The invention relates to a waveguide comprising two walls, called guide walls (21), each guide wall (21) forms: - at least two surfaces, called multimode surfaces (80): ○ extending along said axis propagation in a plane, called multimode plane, o a multimode surface being spaced from a multimode surface of the other guide wall by a distance of value a, - at least one other surface, called surface (81) of adaptation: ○ extending along said propagation axis in a plane, called adaptation plane, between the multimode planes of the guide walls, ○ arranged between two multimode surfaces of the same wall, an adaptation surface of a guide wall being spaced from an adaptation surface of the other guide wall by a distance of value b, a and b being chosen to allow the simultaneous and selective propagation of two orthogonal propagation modes.
