The presented article proposes an improved design of a controllable cylindrical hyperlens based on alternating layers of indium antimonide and silicon. This design is intended for obtaining sub-wavelength resolution images in the terahertz range. Using numerical simulation, the ability of dynamic tuning of the hyperlens over a wide frequency range by varying the temperature is demonstrated. The key characteristics of this structure include small dimensions, low losses in the dielectric, and the ability to form images with super-high resolution. This research can contribute to enhancing the resolution of visualization systems in the terahertz range, as well as promoting the development of ultra-high resolution imaging and probing systems operating in this range.
