Abstract

Surface waves are electromagnetic waves that are bound to the interface between to media. Zenneck surface waves, the subject of this thesis, have been known about for more than a century. Most recent research has been either very academic in nature or has focused on how to attenuate or stop them propagating with surface waves in general being considered a nuisance and an inefficiency. However, it is the opinion of the author that the Zenneck surface wave has several properties that could provide significant advantages over traditional three-dimensional (3D) wireless communications techniques and one-dimensional (1D) wires in some applications. Yet, to date, no one has utilised its unique and potentially highly useful properties. This research has extended the many existing studies to much higher frequencies, for the first time practically demonstrating Zenneck surface wave propagation above 20 GHz. It has also produced pioneering proof of principle demonstrations at 24 GHz and 60 GHz to prove the assertion that Zenneck surface waves are a viable alternative to existing wired and wireless solutions. To the author’s knowledge, this is the first piece of work to quantitatively assess the loss associated with corners through either simulations or measurements. It is this author’s assertion that this research has reinvigorated Zenneck surface waves as an area of research with Newcastle University recently employing a PhD student to study the utility of Zenneck surface waves for on-chip and off-chip interconnects.
