Because it lies between the radio frequencies and infrared wavelengths, the terahertz electromagnetic region was thought to be promising for practical applications （300 micrometers wavelength corresponds to 1 THz frequency）, but it suffered from very high attenuation through the atmosphere （above 1 dB/meter）, and was found to be difficult to generate, modulate, and detect. On the other hand, many non-polar dielectric materials are transparent to THz waves,展开更多
