Abstract
Micromilling technologies are used to design and experimentally study terahertz power reflecting optical elements with free-form surfaces. The results of the experimental study are in good agreement with theoretical estimates. It is shown that the technique used in this paper makes it possible to develop terahertz focusing reflecting elements with energy efficiency above 94 %.
