The model of receiving area of detector based on VOx film is suggested in this paper. Receiving area consists of a thin mica substrate covered with frequency-dependent metal surface on the front side and thermosensitive VOx elements with electric circuit on the backside. The absorption of THz radiation by receiving area is investigated. The radiation detection is studied numerically and experimentally in the range 1.3−1.6 THz. In conclusion, the exploitation parameters of the device are determined.
