Coupling and propagation of Sommerfeld waves at 100 and 300 GHz

May 14, 2019February 5, 2014 by JP

The coupling between a linearly-polarized gaussian beam and a Sommerfeld wave propagating on a circular metallic wire is obtained owing to a differential phase element inserted in front of the metal wire. At millimeter-wavelengths we calculate a theoretical maximum coupling efficiency of 32% for this system in spite of the metal nature and radius in … Read more
