英文摘要：

Thermal emission characteristics of a negative index semitransparent thin film were studied based on transmit matrix method and Kirchhoff radiation law. The influence of different parameters on the emissivity of s-polarization wave was studied. The results show that a complicated oscillation will happen when the angular frequency increases. It also shows that the peak value of the emissivity is sometimes far away from the normal direction.
