IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe propose a new perturbative treatment of the equations for electromagnetic wave propagation in the adjabatic limit in liquid crystals where the director is continuosly rotatin through the sample with an arbitrary law. In this approach a simple, 2×2 Jones matrix is obtained by proper transformation of the conventional 4×4 Berreman matrix. An approximate propagation equation is deduced for the jones Vector giving the polarization state of the wave propagating in the forward direction. The results obtained by using this equation are compared with the exact ones and the limits of validity of the present approach are discussed.
