DEVICE FOR COUPLING AN ELECTROMAGNETIC WAVE BETWEEN A WAVEGUIDE AND A SLIT METAL GUIDE, METHOD FOR MANUFACTURING SUCH A DEVICE, AND OPTICAL AND ELECTRIC COUPLER FOR AN OBJECT USING THE OPTICAL COUPLING DEVICE

摘要

The device for coupling an electromagnetic wave includes a waveguide and a slit metal guide. The slit metal guide is formed by two metal elements which are coplanar and spaced out from one another so as to form the slit. The slit metal guide is arranged in a plane offset from the plane of the waveguide and partially covers said waveguide, said waveguide and the slit guide being maintained at a distance from one another by a dielectric.
