ABSTRACT:
A fluid-tight coupling device for microwave radiation of high energy incls a tubular dielectric window which is sealingly connected to one end of a waveguide supplying the microwave radiation and forms a continuation of the waveguide. The other end of the tube forming the window is tightly sealed by an essentially conical reflector. The tube forming the window is surrounded on the outside by a cup-shaped waveguide portion. The reflecting surface of the reflector and the reflecting inner surface of the cup-shaped waveguide portion are formed such that the microwave radiation emerging from the waveguide is reflected through the tubular window into the cup-shaped waveguide portion and from the latter to the open end of the waveguide portion in such a manner that an input mode of type TE.sub.mn is transformed into itself or a well-defined adjacent mode TE.sub.m'n', further secondary modes are minimized and at the same time return waves are also minimized. Due to the cylidrical form a window area of one or two orders of magnitude larger than in the known plane windows is obtained and thus a correspondingly smaller area stress so that even very high microwave powers can be transmitted.
