Abstract: Radio-wave devices are used for many environmental and material research tasks. These devices and the development of relatively simple and affordable quasi-optic radio wave receivers and transmitters of millimeter and terahertz bands are important for numerous applications. Results of the design of a terahertz-band quasioptical transmitter-receiver module are presented. The module is intended for the remote detection of various objects and for measuring the depolarized field components backscattered by various long objects hidden behind obstacles (building materials and/or everyday items that prevent visual contact with the objects). These may be interfaces between materials with different dielectric constants, fiber optic cables, electric cables, and other objects. Results of full-scale experimental testing of the module on the detection of electric cables buried under plater in the wall of a building are presented.

Keywords: microwave module, millimeter and terahertz bands, quasi-optical devices, waves depolarization effect
