Abstract
The invention concerns electromagnetic wave guides. It has as its object a wave guide comprising a hollow conductor consisting of layers of porous dielectric or conductive materials, bound together and to the hollow conductor by a resinous compound, at ambient temperature, in a very short time, in contact with a gaseous catalyst. It is applied, to great advantage, to the continuous manufacturing of wave guides.
