Coaxial microcavities etched into the surface of a doped silicon substrate are shown to support localized surface plasmon resonances at terahertz frequencies. This provides a promising pathway for the development of terahertz devices with application in the areas of photonic integrated circuits, molecular sensing, and subwavelength imaging.
