Abstract : The variety of waves which can be supported by a plane homogeneous interface is viewed as contributions due to poles in several alternative integral representations of a source-excited field, with particular stress placed on the steepest-descent representation. The pole locations, field istributions and power transport properties are explored in detail for all of the wave types. Distinctions are made between proper (spectral) and improper (leaky) waves and between lossy and lossless structures; complex waves along lossless structures are shown to appear always in degenerate pairs consisting of a forward and a backward wave, with interesting power flow characteristics. The different wave types are grouped into the general category of complex guided waves which propagate without attenuation as inhomogeneous slow plane waves at some angle with respect to the interface. Power transport considerations via the steepest-descent representation show that these waves either carry power to compensate for losses in the system or account for a transfer of energy int the radiation field.
