We show that a Fabry–Perot-like tunneling cantilever consisting of two parallel thin metallic cantilevers joined at their free ends is able to sense the power of an incoming terahertz (THz) field. An array of such microstructures, with linearly varying distances between the two parallel cantilevers, can measure simultaneously the power and frequency of the THz field in the bandwidth 1.2–58 THz. © 2001 American Institute of Physics.
