HYPERBOLIC STRUCTURE METAMATERIALS FOR TERAHERTZ MODULATION AND SUBWAVELENGTH IMAGING
Description, purpose:
Hyperbolic metamaterials are of great interest for possible solutions for obtaining images in real time with a resolution exceeding the diffraction limit due to the creation of hyperlenses.
Active hyperlenses have a wide range of applications in the field of non-destructive testing of materials, quality control, medical diagnostics. Terahertz hyperbolic metamaterials can also be used in security systems. They are able to detect an object hidden inside the package due to their ability to penetrate many non-polar materials.
Field of application
The active hyperbolic structures of metamaterials make it possible to use it as a potential application for visualization and sensing with super-resolution in real time.
Technical and economic advantages
Conventional terahertz imaging and sensing systems are static and frequency dependent. The proposed active hyperlens has dynamically changing characteristics due to the use of materials such as graphene and indium antimonide. Both materials make it possible to perform frequency tuning in a wide range in the terahertz range, to obtain an image with super-resolution in both the near and far zones in real time, and even to increase it.
The layered structure of the hyperlens is relatively easy to manufacture, ultra-compact and cheaper than modern high-resolution sensors or matrix detectors.
The use of active hyperlens in medicine will simplify the non-destructive visualization of living tissues and biological samples.
