We investigate the thermal antenna behavior of emissive/absorptive substrates coated by passive optical multilayer systems that contain negative refractive index metamaterials (NIM). Spectral and angular distributions of the thermal radiation emittance for periodic defect-containing multilayer with NIM is addressed. We analyze realistic finite structures and took into account dispersion and losses in the NIM part. The application of NIM-containing 1D structures offers new degrees of freedom for the design, thus opening a path to obtain spectrally and spatially selective thermal emitters that could lead to improvements in the existing systems for thermal radiation control.
