  abstract = {The terahertz (THz) range of the electromagnetic spectrum is considered for data transmission, including future 6G networks. This work focuses on modeling and analyzing a THz optical system using off-axis parabolic mirrors (OAPMs) for collimation and focusing of radiation from a 140 GHz IMPATT diode. Experimental directivity patterns were approximated with a Gaussian distribution and implemented in simulation. The system achieved about 85% power transfer efficiency in modeling and 40% experimentally. The use of OAPMs significantly improves beam collimation, increases peak intensity, and extends transmission range without increasing source power, though additional tracking systems are required.},
