  4. Abstract:
  5. We have modelled and simulated a simple THz spectroscopic system to identify materials. A Vivaldi antenna with suitable specifications was used as a transmitter in the simulation. In order to characterize the object, we applied two different methods based on the derivative of the reflectivity and the Kramers-Kronig relations. Also, to obtain the optimized incident angle, we calculated the reflection sensitivity of the sample to the angle of incidence using the Fresnel equations and verified our result by simulation. © 2021 IEEE
