PROCEDE DE CARACTERISATION DE MATERIAU DIELECTRIQUE EN FILM MINCE DANS LE DOMAINE DE L'INFRAROUGE LOINTAIN ET DISPOSITIF ET BANC DE MESURE POUR LA MISE EN OEUVRE D'UN TEL PROCEDE |
摘要 |
<p>The invention relates to a method and a device for characterising a thin film (2). The device (1) defining a wave guide includes a substrate (10) of a transparent material with parallel faces (100, 101) with a diffraction network (102) on one face (100). A wave parallel network THz is projected on the network (102) at a predetermined incidence angle and the energy transmitted is measured with or without a film (102) on the other face (101). The transmitted energy has minimal values for certain frequencies that differ depending on the film (2) being present or not. The differential analysis of the minimal values with and without the film (2) is used for determining the electromagnetic parameters of the film material.</p> |
