Ellipsometric measurement of the complex refractive index of liquids in the terahertz range


  • Mr. Ivan AZAROV

Primary authors



Complex refractive index of various liquids has been measured in the THz range using the ellipsometric measurement system with an internal reflection silicon-prism with the Novosibirsk free electron laser being a source of monochromatic radiation . The measurement technique has been optimized both theoretically and experimentally for water solutions. Precision of the measurement of the absolute values of the real and imaginary parts of the refractive index (n, k) equal to 0.01 is achieved experimentally.
