Abstract: | Experimental and theoretical study of thermal emission, transmission, and reflection from bare and coated one-dimensional
(1D) and two-dimensional (2D) grating structures on GaAs substrates was carried out. Our experiments have revealed strong
correlation between the spectra of thermal emission and the microstructure dimensions. The emissivity enhancement and diminution
depends on the groove depth and the spectral range (below or above Rayleigh wavelength). The effects can be attributed to
diverse mechanisms: emission escape due to emerging diffraction-order beams, vertical-cavity modes, enhanced optical transmission
phenomenon, and electron plasma effect. |
