Electromagnetic surface waves were observed in single surface corrugated guides and in lossy single wire transmission line. We analyzed the surface wave behavior in our Sub-THz accelerating structure tests. We tested at the FACET facilities two types of accelerating structures: 130 GHz and 235 GHz travelling wave made of copper. Both structures are open type, composed by two halves that never get in contact with each other. The surface wave arises when the two half parts have a big gap between each other. There is no radiation and the electromagnetic field is guided in an open waveguide
