Thin-film structures can act as directional thermal radiation sources. This novel effect, driven by mode quantization within the structure, offers broad spectral emission for both p- and s-polarized light.

Area of Science:

  • Optics and Photonics
  • Materials Science
  • Thermal Physics

Background:

  • Thin-film structures are crucial in optical devices.
  • Efficient thermal emitters are sought for various applications.
  • Existing methods like gratings have limitations.

Purpose of the Study:

  • To demonstrate thin-film structures as directional thermal radiation sources.
  • To explore the underlying physical mechanism of this emission.
  • To present a novel approach distinct from grating-based methods.

Main Methods:

  • Theoretical analysis using the matrix transfer method.
  • Modeling of mode quantization within thin-film structures.
  • Investigation of emission properties for p- and s-polarized light.
