  • Waveguide obtained by selective etching method
    Patent number: 4818962
    Abstract: The invention provides mainly a selective etching method for the total or partial chemical ablation at certain positions of a metal sheet, and a waveguide obtained by said method. Complete ablation is obtained by etching both faces of the metal sheet. Partial ablation is obtained by etching only one of the faces of the metal sheet. Partial ablation allows grooves and semi-thicknesses to be obtained for forming bends and rabbets for the formation of three dimensional pieces.
