Abstract
A multi-layer waveguide device, a multi-layer waveguide arrangement, and a method for production thereof, wherein the multi-layer waveguide comprises at least three horizontally divided layers assembled into a multi-layer waveguide. The layers are at least a top layer, an intermediate layer, and a bottom layer, wherein each layer has through going holes extending through the entire layer. The holes are arranged with an offset to adjacent holes of adjoining layers creating a leak suppressing structure.
Claims16
A multi-layer waveguide device comprising:
- at least three horizontally divided layers assembled into a multi-layer waveguide, wherein
- the at least three horizontally divided layers are at least a top layer, an intermediate layer, and a bottom layer,
- each of the at least three horizontally divided layers has respective through going empty holes extending through an entirety of the respective layer, and
- the respective through going empty holes are arranged with an offset with respect to adjacent through going empty holes of adjoining layers thereby creating a leak suppressing structure.
A method for producing a multi-layer waveguide device, the method comprising:
- etching or laser cutting through going holes of a top layer of the multi-layer waveguide device, the through going holes surrounding an elongated area in a center area of the top layer,
- etching or laser cutting through going holes of at least one intermediate layer of the multi-layer waveguide device, the through going holes surrounding an elongated area in a center area of the at least one intermediate layer,
- etching or laser cutting an elongated aperture into the elongated area of the at least one intermediate layer, and
- etching or laser cutting through going holes of a bottom layer of the multi-layer waveguide device, the through going holes surrounding an elongated area in a center area of the bottom layer.
