The search for alternative plasmonic materials with improved optical properties, easier fabrication and integration capabilities over those of the traditional materials such as silver and gold could ultimately lead
to real-life applications for plasmonics and metamaterials. In this work, we show that titanium nitride could perform as an alternative plasmonic material in the visible and near-infrared regions. We demonstrate the
excitation of surface-plasmon-polaritons on titanium nitride thin films and discuss the performance of various plasmonic and metamaterial structures with titanium nitride as the plasmonic component. We also show that
titanium nitride could provide performance that is comparable to that of gold for plasmonic applications and can significantly outperform gold and silver for transformation-optics and some metamaterial applications in the visible and near-infrared regions.

La búsqueda de materiales plasmónicos alternativos con propiedades ópticas mejoradas, una fabricación más sencilla y mejores capacidades de integración respecto a los materiales tradicionales tales como la plata o el oro podría permitir aplicaciones en la vida real en plasmónica y en metamateriales. En este trabajo se muestra que el nitruro de titanio podría desempeñarse como un material plasmónico alternativo en las regiones del cercano infrarrojo y del visible. Se demuestra la excitación de polaritones plasmónicos de superficie sobre películas delgadas de nitruro de titanio, y se discute el desempeño de diversas estructuras metamateriales y plasmónicas con nitruro de titanio como componente plasmónico. También se muestra que el nitruro de titanio podría permitir un desempeño comparable al oro en aplicaciones plasmónicas, e incluso supera significantemente el desempeño del oro y la plata en óptica de transformación y en algunas aplicaciones de metamateriales en las regiones visible y del cercano infrarrojo.
