ABSTRACT:
An innovative nonradioactive dielectric waveguide (NRD guide). Protrusions are separately formed on a surface of a dielectric strip. Recesses corresponding to the protrusions are formed on a parallel conductive plate. The dielectric strip is set between top and bottom parallel conductive plates such that the small protrusions on the dielectric strip are fitted into the recesses on the bottom parallel conductive plate.
