A study on impulse response model of reflected path for THz band

Impulse response based channel model is vital for wireless communication analysis and modeling. This paper considers the impulse response of the terahertz band (THz band: 0.1-10 THz) for reflected path in case of short range (1–100 cm) wireless communication. In indoor application, it is necessary to consider multipath channel. In analysis of reflected path, rough surface of reflector is considered with Rayleigh roughness factor. The validity of the model is investigated with experimental THz band measurements (up to 2THz).
