Material Analysis To Achieve High Field Confinement For Effective Surface Wave Communication

The surface wave communication-based wave-guide best suits for inter chip communication in replacement to the copper traces due to its efficacy in dealing with the losses mitigation at higher frequency ranges. The design of such waveguide requires the consideration of field confinement which defines the intensity of the field concentration at the interface of conductor and dielectric of the surface wave based wave-guide. This article explains the analytical view in choosing the right materials of conductor and dielectric for the wave guide construction in terms of field confinement. The higher field confinement outcomes the lesser dispersion which considered as the important factor for losses suppression. Several conductor and dielectric materials have been analyzed in terms of high field confinement levels at 0.5μm and l.2μm wavelengths establishing high frequency mode. The outcome of the analysis comes with aluminum and glass combination possess high field confinement in terms of γ/αd ratio as 53 for l.2μm and 14.04 for 0.5μm. This also proves that the field confinement for extensive losses reduction increases with the increased propagation frequency.
