Abstract
The invention relates to a method of manufacturing a waveguide device including a step of producing, by additive manufacturing, a semi-finished metal core having side walls having external and internal surfaces, the internal surfaces defining an internal waveguide opening. The manufacturing process further includes a step of chemically polishing the metal core to reduce the thickness of the side walls by an ablation thickness equal to at least twice a roughness of the metal core before polishing, to obtain the waveguide device. The invention also includes a waveguide device obtained according to the above-mentioned process.
