Abstract
A structure can include a first element and a carrier bonded to the first element along an interface. A waveguide can be defined at least in part along the interface between the first element and the carrier. The waveguide can comprise an effectively closed metallic channel and a dielectric material within the effectively closed metallic channel, as viewed from a side cross-section of the structure. Various millimeter-wave or sub-terahertz components or circuit structures can also be created based on the waveguide structures disclosed herein.
