Abstract

An investigation has been performed of the low order guided modes in TiN 2D hollow metallic waveguide. The dispersion characteristics of the TiN 2D hollow metallic waveguides key guided modes are identified and analyzed. Dispersion manipulating is proposed by changing the material of the cladding region. The dispersion analysis of 2D plasmonic waveguide using TiN has been investigated for the first time and compared to that of silver. A study has been conducted on the effect of varying the material on the cutoff in the modes dispersion. The effect of changing the plasmonic material on the dispersion curve key characteristics is also identified. Finally the effect of shifting the cutoff on the enhanced transmission phenomena is investigated.
