Abstract
A method for depositing an electrically conductive metal onto at least one portion of the inner surface (3) of an internal cavity (2) of a waveguide (1) includes: preparing a suspension containing at least one liquid and at least one precursor of the electrically conductive metal in suspension in said at least one liquid; coating at least one portion of the inner surface (3) of the internal cavity (2) of the waveguide (1) with the suspension, and heat-treating at least said portion of the inner surface (3) of the internal cavity (2) of the waveguide (1) coated with the suspension. A method for manufacturing a metallized waveguide can implement this deposition method.
