Electromagnetic wave launcher including an electromagnetic waveguide, wherein a millimeter wave signal and a lower frequency signal are respectively launched at different portions of the waveguide

摘要

There is disclosed in one example an electromagnetic wave launcher apparatus, including: an interface to an electromagnetic waveguide; a first launcher configured to launch a high-frequency electromagnetic signal onto a first cross-sectional portion of the waveguide; and a second launcher configured to launch a lower-frequency electromagnetic signal onto a second cross-sectional portion of the waveguide.
