Methods of fabricating a channel waveguide for electromagnetic waves and a structure atenuadora for electromagnetic waves.The channel waveguide structure for electromagnetic waves and to attenuate electromagnetic waves ".To fabricate waveguides, for example channels of guided wave tightly constituu00ecdos for electromagnetic waves such as microwaves.The channels are produced from bodies in the form of a stem (1) of a material permeable to waves and not significantly attenuating waves.The bodies (1) can for example out of a base plate (3) and its side surfaces are coated with electrically conductive material but not extreme free surface (5).The interior of the bodies to form the waveguide channels, which have their walls formed from the layer of electrically conductive material.By giving the bodies in the form of a probe suitable profiles for example one side dish or half of an antenna waveguide can be manufactured.The bodies in the form of a shank can before the application of electrically conductive material to be coated with one or several layers of lacquer non attenuating non conductive filling the pores and there.Sando the surface of the body.In this way, the layer of electrically conductive material obtains a smooth transition surface for the material of the bodies with the channels good characteristics of guided wave.The material used in the bodies has a strong surface porosity, the channels formed of the bodies in the form of a stem become strongly attenuators for electromagnetic waves.A set of such bodies located at the sides of each other and having suitable dimensions of the bodies results in an element strongly working as buffer for the electromagnetic waves.
