Abstract: A waveguide device is provided to absorb or dissipate electromagnetic waves. The device comprises an elongated housing having a first end that is a power receiving end and a second end, the housing defining a hollow passage. The device also has an elongated absorber element disposed within the hollow passage of the housing along an interior surface of the housing. The elongated absorber element is configured to absorb at least part of electromagnetic waves traveling through the hollow passage. The device also has a projection extending from the elongated housing into the passage. The projection is configured to exert a resilient force on the absorber element to urge the absorber element against the interior surface of the housing. A method for assembling the waveguide device is also provided.

Abstract: A cross-guide coupler for use in a waveguide network is provided. The cross-guide coupler comprises a main waveguide arm having an input port and a transmitted port and a hollow metallic conduit therebetween. The cross-guide coupler also comprises a secondary arm positioned substantially transversely relative to the main arm and being fastened to the main arm, wherein the secondary arm includes a substrate integrated waveguide.
