• The terahertz spectrum of matter contains many physical and chemical information


  • Insensitive to blackbody radiation, high signal-to-noise ratio, stable measurement
  • Low-energy electromagnetic waves that do not harm biological tissues
  • Pass many common materials, suitable for non-destructive testing


  • Using the XPS array made of metamaterials combined with the design of the microchannel, a small chip can be used with terahertz technology to analyze the object
  • After the terahertz radiation penetrates the microchannel of the wafer and is filled with different substances, it can be seen that its spectrum is significantly different and has a specific waveform
