Opis

This book covers terahertz antenna technology for imaging and sensing, along with its various applications. The authors discuss the use of terahertz frequency and photoconductive antenna technology for imaging applications, such as biological and bio-medical applications, non-destructive inspection of fabrics and plastics, analysis of hydration levels or detecting the presence of metallic components in samples, and detecting a variety of materials with unique spectral fingerprints in the terahertz frequency range, such as different types of explosives or several compounds used in the fabrication of medicines.

• Provides a comprehensive review of terahertz source and detector for imaging and sensing;
• Discusses photoconductive antenna technology for imaging and sensing;
• Presents modalities for improving the photoconductive dipole antenna performance for imaging and sensing;
• Explores applications in tomographic imaging, art conservation and the pharmaceutical and aerospace industries.
