A method and apparatus for enhanced THz radiation coupling to molecules, includes the steps of depositing a test material near the discontinuity edges of a slotted member, and enhancing the THz radiation by transmitting THz radiation through the slots. The molecules of the test material are illuminated by the enhanced THz radiation that has been transmitted through the slots, thereby producing an increased coupling of EM radiation in the THz spectral range to said material. The molecules can be bio- molecules, explosive materials, or species of organisms. The slotted member can be a semiconductor film, a metallic film, in particular InSb, or layers thereof. THz detectors sense near field THz radiation that has been transmitted through said slots and the test material.
Procédé et dispositif de couplage amélioré du rayonnement Thz à des molécules, comprenant les étapes de dépôt d'un matériau de test près des bords discontinus d'un élément fendu, et d'amélioration du rayonnement THz par transmission du rayonnement THz à travers les fentes. Les molécules du matériau de test sont illuminées par le rayonnement THz amélioré transmis à travers les fentes, ce qui améliore le couplage du rayonnement EM dans la plage spectrale des THz audit matériau. Les molécules peuvent être des biomolécules, des matériaux explosifs, ou des espèces organiques. L'élément fendu peut être un film semi-conducteur, un film métallique, en particulier un InSb, ou des couches de celui-ci. Les détecteurs THz détectent le rayonnement Thz de champ proche transmis à travers lesdites fentes et le matériau de test.
