Waveguides interconnected by flanges having glide symmetrically positioned holes disposed therein

A first waveguide comprising:

• a first flange surrounding an end opening of the first waveguide;
• wherein the first flange comprises at least two holes which are periodically distributed around the end opening;
• and
• wherein the first waveguide is configured to be connected to a second waveguide, wherein the second waveguide comprises a second flange surrounding an end opening of the second waveguide and wherein the second flange comprises a corresponding at least two holes which are periodically distributed around the end opening of the second flange, by connecting the first flange to a second flange such that the end opening of the first waveguide faces the end opening of the second waveguide, and such that the at least two holes of the first flange are at least partly glide symmetrically positioned with respect to the corresponding at least two holes of the second flange.

A waveguide assembly, the waveguide assembly comprising:

• a first waveguide comprising a first flange surrounding an end opening of the first waveguide;
• wherein the first flange comprises at least two holes which are periodically distributed around the end opening of the first waveguide;
• a second waveguide comprising a second flange surrounding an end opening of the second waveguide;
• wherein the second flange comprises at least two holes which are periodically distributed around the end opening of the second waveguide;
• wherein the first and second waveguides are configured to be connected to each other by connecting the first flange to the second flanges such that the end openings of the first and second waveguides face each other and such that the at least two holes of the first flange are at least partly glide symmetrically positioned with respect to the at least two holes of the second flange.

A method for manufacturing a first waveguide, the method comprising:

• providing a first flange surrounding an end opening to the first waveguide;
• wherein the first flange comprises at least two holes which are periodically distributed around the end opening;
• and
• wherein the first flange of the first waveguide is configured to be connected to a second flange of a second waveguide, wherein the second flange comprises at least two holes which are periodically distributed around an end opening of the second waveguide, by connecting the first flange to the second flange such that the end opening of the first waveguide faces the end opening of the second waveguide, and such that the at least two holes of the first flange are at least partly glide symmetrically positioned with respect to the at least two holes of the second flange.
