Abstract
In this work, we propose a composite multilayer structure consisting of a Weyl semimetal (WS) film and photonic crystal (PC) with a defect layer to achieve nonreciprocal thermal radiation with high quality factor. This high quality factor results from the strong coupling between Tamm plasmon (TP) and defect mode (DM). The quality factor of nonreciprocal thermal radiation can be as high as 221.27 at a wavelength of 9.736 μm. The magnetic field distribution inside the structure and the reflection spectrum of the photonic crystal are also shown, which is beneficial to reveal its physical mechanism. Based on the variation of absorption and emission spectrum with different defect layer thicknesses, the splitting appears in the figure, which proves the strong coupling between Tamm plasmon and defect mode. We believe that these results will provide a new way to realize nonreciprocal thermal radiation applications.
