Large ohmic losses in metal is the main factor impeding the progress in plasmonics and metamaterials. An extensive effort to replace metals as materials of choice, especially in the infrared region of the spectrum with alternative materials, such as high-doped semiconductors, nitrides, or “Phononic” materials is currently under way. In this talk I will offer a critical assessment of how the alternative plasmonic materials stack up against noble metals in the infrared region and show that they face an uphill battle in the quest to replace metals.
