Abstract
Terahertz radiation lies between far-infrared and microwave in electromagnetic spectrum with frequency from 0.1 to 10 THz. Absorption spectra of different mass ratio of the myrrh and polyethylene can be gained by Fourier transform infrared spectrometer in this paper. It is found that absorption spectra show a slight red-shift with the decrease of the mass ratio of myrrh and polyethylene. On the other hand, different particle sizes of polyethylene (PE) mixed with myrrh absorption spectra were measured. Due to the different sizes of polyethylene particles, there are some differences in the vibration peak intensity, peak position and peak numbers in the absorption spectra. The experimental results show that the scattering effect leads to this phenomenon.
