Voigt configuration

Figure 5. Photoluminescence spectra of ZnO N in the energy region of the 12/13 hnes at 4 2 K for different magnetic fields in Faraday configuration (case (a) B // k // c, E c) and Voigt configuration (case (c) B c, k // c, E L c), and for different angles between the c axis and the direction of the magnetic field B at 5 T (case (b)).

The magnetic field splits this state into a triplet with Mj = +1, 0, and — 1, whose energy levels Em depend on A and on the orbital and spin g factors < l and < s. The transition to the Mj = 0 state is a so-called n transition with E//B polarization, which can be observed only in the Voigt configuration while those to the Mj = 1 states are o transitions with ETB polarization, which are seen only in the Faraday configuration. The linear Zeeman term of a 3T2 state with a magnetic field B may be written as ... 

Fig. 8.30. Magnetic-field dependence of the Zeeman splitting of the Is (3T2) line of Se° in silicon measured at 1.7 K in the Voigt configuration for three orientations of the sample. The theoretical curves (solid lines) are the same for each orientation (after [120]). Copyright 1988 by the American Physical Society...

The tissue has been modeled from a continuum mechanics point of view by Jfow and students (11,12,13). The model treats cartilage as a blphaslc material (the solid"organic matrix was assumed, for these purposes, to be one "phase" and the water the other). The "solid" organic matrix was further assumed to behave as a single Kelvln-Voigt body whose viscoelastic properties are attenuated by the frictional resistance to fluid flow from the tissue. Attempts were made to use this model to explain the load-strain and load dissipation properties of the tissue for the experimental configuration described In this paper (15),... 

In addition, a time-dependent viscoelastic component described by the so-called Voigt-Kelvin configuration, i.e. the combination of spring E and damper Yf comes into action. Further, a viscoplastic flow component may exist, modelled by the damper of viscosity...
