| Abstract: | An improved design of a controlled cylindrical hyperlens based on alternating layers of indium antimonide and silicon for imaging with a subwave resolution in the terahertz range is proposed. A possibility of dynamic tuning of hyperlens in a wide frequency range at small variations is temperature is demonstrated by numerical simulation. Distinctive features of this structure are small sizes, low loss in the insulator, and the ability of forming images not only in the near-field zone but also in the far-field zone, which was confirmed by plotting directional patterns. Based on the proposed computer model, a cylindrical hyperlens can be fabricated using conventional methods of deposition or electron-beam evaporation. The results obtained may contribute to improvement of the resolution of imaging systems in the terahertz range and development of modulators of hyperbolic metamaterials and sensors in the terahertz range.
