Special Issue Information

Dear Colleagues,

Terahertz science and technology has attracted extensive attention recently because of its promising application prospects in the industrial field, ranging from short-range wireless communication to nondestructive Evaluation. This Special Issue, ‘Terahertz Optics and Spectroscopy’, aims at highlighting advances and developments in terahertz spectroscopy and technology, with a particular focus on terahertz time-domain spectroscopy, terahertz imaging, AI-assisted super resolution imaging reconstructed algorithms, and practical applications.

We cordially invite researchers, engineers, and practitioners to share innovative insights and present significant theoretical and experimental developments, as well as specific case studies in the field of terahertz imaging and spectroscopy. Research areas may include (but are not limited to) the following:

  • THz imaging;
  • THz time-domain spectroscopy;
  • THz-related engineering application;
  • Data processing for terahertz spectroscopy and imaging;
  • Nondestructive evaluations;
  • 6G wireless communication;
  • Terahertz radiation sources and detectors.

The subject of this Special Issue is highly relevant to the scope of the Electronics journal, which provides a forum for researchers and engineers to publish their cutting-edge research on the science of electronics and its applications. We encourage contributors to submit manuscripts that address these themes, providing innovative insights and robust solutions to all aspects of basic research and diverse applications related to terahertz photonics.

While electromagnetic metamaterials completely revolutionized optics and radio frequency engineering, recent progress in the development of conceptually related electronic metamaterials was more slow. Similar to electromagnetic metamaterials, which engineer material response to the electromagnetic field of a photon, the purpose of electronic metamaterials is to affect electron propagation and its wave function by changing material response to its electric field. This makes electronic metamaterials an ideal tool for engineering light–matter interaction in semiconductors and superconductors. Here, we propose the use of Fermi’s quantum refraction, which was previously observed in the terahertz spectroscopy of Rydberg atoms and two-dimensional surface electronic states, as a novel tool in quantum electronic metamaterial design. In particular, we demonstrate several potential applications of this concept in two-dimensional metamaterial superconductors and “universal quantum dots” designed for operation in the terahertz frequency range.
