It is shown that the metallic disk structure can be used as an efficient narrow-band thermal emitter in the IR region. The absorption spectra of such structure are investigated both theoretically and experimentally. Calculations of thermal radiation properties of the metallic disk show that the metallic disk is a perfect emitter at a specific wavelength. The metallic disk exhibits only one significant localized surface plasmon polariton mode for both TM and TE polarizations simultaneously.
